Answer: 305 g of Be_3(PO_4)_2 will be produced from 38 grams  of beryllium oxide

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} BeO=\frac{38g}{25g/mol}=1.52moles

3BeO+2FePO_4\rightarrow Be_3(PO_4)_2+Fe_2O_3

According to stoichiometry :

3 moles of BeO produce = 1 mole of Be_3(PO_4)_2

Thus 1.52 moles of BeO will produce =\frac{1}{3}\times 1.52=0.507moles  of Be_3(PO_4)_2

Mass of Be_3(PO_4)_2=moles\times {\text {Molar mass}}=0.507moles\times 602g/mol=305g

Thus 305 g of Be_3(PO_4)_2 will be produced from 38 grams  of beryllium oxide

Can someone help Plz
Marrrta [24]

Answer: A. 1.60 liters

Explanation:

2Na_2O_2+2CO_2\rightarrow 2Na_2CO_3+O_2

As can be seen from the balanced chemical equation, 2 moles of CO_2 produce 1 mole of O_2.

According to Avogadro's law, every 1 mole of the gas occupies 22.4 liters at STP.

Thus 2 moles of CO_2 occupies 22.4\times 2=44.8L at STP and produce 1 mole of O_2 i.e. 22.4 L

44.8 L of CO_2 will produce 22.4 L of O_2

Thus 3.20L of CO_2 will produce \frac{22.4}{44.8}\times 3.20=1.60L
