Question

52 g of Helium (He) there are --------'moles of Helium (atomic mass of He 4 g per mol) *​

Answer 1

Answer:

13

Explanation:

as moles=given mass / molecular mass

moles=52/4=13 moles

Answer 2

Molar mass of Helium =4g

Molar mass of Helium =4gThe given mass of Helium =52g

Molar mass of Helium =4gThe given mass of Helium =52gThus the number of moles of Helium =givenmass/molarmass

Molar mass of Helium =4gThe given mass of Helium =52gThus the number of moles of Helium =givenmass/molarmass =52/4

Molar mass of Helium =4gThe given mass of Helium =52gThus the number of moles of Helium =givenmass/molarmass =52/4 =13
