6,02*10^{23} \ \ \ \rightarrow \ \ \ 22,4dm^{3}\\
5,2*10^{26} \ \ \ \ \ \rightarrow \ \ \ V_{x}\\\\
V_{x}=\frac{5,2*10^{26}*22,4dm^{3}}{6,02*10^{23}}\approx 19,35*10^{3}dm^{3}=19350dm^{3}

The recommended daily allowance (rda of calcium is 1.2 g. calcium carbonate contains 12.0% calcium by mass. how many grams of ca
defon
1) Calcium carbonate contains 40.0% calcium by weight.
M(CaCO₃)=100.1 g/mol
M(Ca)=40.1 g/mol
w(Ca)=40.1/100.1=0.400 (40.0%)!

2) Mass fraction of this is excessive data.

3) The solution is:

m(Ca)=1.2 g

m(CaCO₃)=M(CaCO₃)*m(Ca)/M(Ca)

m(CaCO₃)=100.1g/mol*1.2g/40.1g/mol=3.0 g
