Question

Calculate the number of mole for following

1)4gm $NaOH$

2)34.2 g Glucose

3)30 g of $H_{2}S{O}_4$

4)100 g of $CaC{O}_3$

Answer 1

a) Number of moles in $4g$ of $NaOH=\frac{4}{40}=0.1$

b) Number of moles in $34.2g$ of glucose $=\frac{34.2}{342}=0.1$

c) Number of moles in $30g$ of $H_{2}S{O}_4=\frac{30}{98}=0.3061$

d) Number of moles in $100g$ of $CaC{O}_3=\frac{100}{100}=1$
