This free calculator allows you to calculate how much to weigh the material to obtain a solution of desired molarity or molality. Also you can calculate molar mass of substances. App contain Periodic table of elements. The help file provides basic concepts and examples.
Via application knowing the molar mass of solute and the molarity of the solution of the substance can be calculated the amount of solute.
The application can be useful to researchers, students and teachers, especially those specializing in molecular biology, biochemistry, microbiology, genetics, chemistry, etc.
The application can read the results of calculations aloud with text-to-speech engine.
1. In the field "Molar concentration" write the molecular weight of the solute. For example, for NaCl mass of the sodium atom is 22.99, the mass of an atom of chlorine - 35,453, a total molecular weight is about 22.99 + 35.45 = 58.44
The masses of the atoms of simple substances can be found in the periodic table, it is called with the "?" or count in the application (click the "Table" button on the right side of the screen)
2. In the field "Molecular weight of the solute" write the desired molarity. If you need any nanomolar or micromolar solution, the application can use the field selection metric prefixes.
3. In the field "Volume of the mixture, ml" write how much we need a solution.
4. Press "Enter".
5. The application calculates the required weight of the substance.
6. Weigh substance.
7. Solute in a volume of the solvent, a little less than the required amount of solution. When dissolution is complete, bring the volume up to the desired value.

In addition, you can calculate the molality of the solution in the application.
Molality, also called molal concentration, is a measure of the concentration of a solute in a solution in terms of amount of substance in a specified amount of mass of the solvent. This contrasts with the definition of molarity which is based on a specified volume of solution (see Wikipedia)

You can calculate the molar mass inside of application
For example, we need to calculate the molar mass of slaked lime Ca(OH)2
Press icon with table.
Press the key with the first letter of the chemical symbol of calcium - in this case, "C". The program will form a list of all the chemical elements, the symbol of which begins at "C" (for example, it will include carbon, cadmium, etc.)

From the list choose calcium. The program displays it at the top of the screen, and displays various
characteristics of calcium. In the center of the screen appears the inscription "Molar mass XXX g/mol", the molar mass

You can edit the molecular weight of the element, for example, change it for uranium from tabular 238.0289 to 235.0439 - molecular weight of a particular isotope. The change will be during the current session.

We repeat the procedure until we introduce the entire formula of the substance.

这个免费的计算器允许你计算出多少来衡量，以获得所需的摩尔浓度或摩尔浓度的溶液中的物质。您还可以计算的物质摩尔质量。应用中是否包含元素周期表。帮助文件提供了基本的概念和示例。
通过应用知道溶质的摩尔质量和该物质的溶液的摩尔浓度，可以计算溶质的量。
应用程序可以被研究人员，学生和教师，特别是那些专门从事分子生物学，生物化学，微生物学，遗传学，化学等有用
应用程序可以使用文本到语音引擎朗读计算的结果。
1.在字段“摩尔浓度”写溶质的分子量。例如，对于钠原子的NaCl的质量为22.99，氯的原子的质量 - 35453，总分子量为约22.99 + 35.45 = 58.44
简单的物质原子的群众可以在周期表中找到，它被称为用“？”或应用程序中的计数（点击在屏幕的右侧的“表”按钮）
2.在字段“溶质的分子量”写入所需的摩尔浓度。如果您需要任何纳摩尔或微摩尔的解决方案，应用程序可以使用字段选择公制前缀。
3.在字段“混合物的体积，ML”写多么需要的解决方案。
4.按 “Enter” 键。
5.应用程序计算物质的所需重量。
6.称量物质。
7.溶质在溶剂中，比所需的溶液的量少一点的体积。当完全溶解后，把音量开到期望值。

此外，你可以计算的应用解决方案的摩尔浓度。
摩尔浓度，也被称为摩尔浓度，是溶质在溶剂中的质量的规定量在物质的量换算的溶液中的浓度的量度。这与摩尔浓度的定义是基于溶液的特定体积（见维基百科）

你可以计算的应用程序内的摩尔质量
例如，我们需要计算熟石灰的摩尔质量的Ca（OH）2
新闻与表图标。
按与钙的化学符号的第一个字母的关键 - 在这种情况下，“C”。该程序将所有形成的化学元素，该符号的开始于“C”的列表（例如，将包括碳，镉等）

从列表中选择钙。该程序在屏幕的顶部显示它，并且显示各种
 钙的特点。在屏幕的中心显示碑文“摩尔质量XXX克/摩尔”，摩尔质量

您可以编辑该元素的分子量，例如，从表格238.0289铀将其更改为235.0439 - 特定同位素的分子量。这种变化将在本届会议期间。
 
我们重复这个过程，直到我们介绍的物质的整个公式。
