Answer:
no of moles of Nacl= 0.6707
no of moles of NO = 0.943
no of moles of CO2 = 113.61
no of moles of CCl4 = 0.000018
Explanation:
To calculate moles we need know their molar mass.
for Nacl2
given mass = 39.2g
molar mass= 58.44g/mol
no of moles =given mass÷ molar mass
= 39.2÷58.44
= 0.6707 mol
for NO
no of moles =28.3÷30.01
= 0.943 mol
for CO2
no of moles = 5000÷44.01 (5kg= 5× 1000g)
= 113.61 mol
for CCl4
no of moles = 0.002÷153.82 (mg to gm)
= 0.000018 mol
