The molar mass of citric acid (c6h8o7) is 192.124g/mol
The molar mass of baking soda (nahco3) is 84.007g/mol
The molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample and is measured in moles. Molar mass is a mass property, not a molecular property of a substance.
Molar mass is the mass of 1 mole of the sample. To find the molar mass, add up the atomic masses (atomic weights) of all the atoms in the molecule. Use the masses listed in the periodic table or atomic weight table to determine the atomic mass of each element.

The group of unsaturated hydrocarbons which 2 carbons are double bonded together, with H bonded to the left, and C H 2 bonded below left, above right, and below right is derived from <u>Alkenes</u>
<h3>What are organic compounds?</h3>
Organic compounds are compounds which contains carbon and hydrogen
Some few classes or organic compounds or hydrocarbons are as follows:
- Alkanes
- Alkenes
- Alkynes
- Alkanols
- Alkanoic acid
- Ketones
- Esters
So therefore, the group of unsaturated hydrocarbons which 2 carbons are double bonded together, with H bonded to the left, and C H 2 bonded below left, above right, and below right is derived from <u>Alkenes</u>

Answer:
0.0102 mole
Explanation:
Use and solve proportions for these with x as the unknown value.
Answer:
The sample of lithium occupies the largest volume.
Explanation:
Given the densities for the four elements, we have the expression that shows the relationship between mass and Volume to express the density of an element.
For each element we have:
The problem says that all the samples have the same mass, so:
it means that m is a constant
Now, solving for the Volume in each element and with m as a constant, we have:
If we assume m = 1g, we find that:
So we can see that the sample of lithium occupies the largest volume with 1.88mL
Note that m only can take positive values, so if you change the value of m, always will be the lithium which occupies the largest volume.
0.2M means 0.2mol CaCl2/1L solution.
This question didn't give us a density of the solution so needs an assumption that the solution has equal volume to water.
xmol/0.5L=0.2M
x = 0.1
0.1mol of CaCl2 is needed. Ca=40g/mol, Cl=35.5g/mol.
CaCl2 0.1mol = (40+35.5*2)*0.1=11.1g
