Question

Q. 11. How many grams are there in:
(i) 5 moles of oxygen, and
(ii) 10 moles of sodium?
(Molar mass of oxygen = 32 g mol and molar
mass of sodium = 23 g mol!)​

Answer 1

Answer:

(i) for oxygen

moles=given mass/molecular mass

5 = G.mass/32

G.mass=5×32 = 160g

(ii) for Na

10 = G.mass/23

G.mass = 10×23 = 230g

hope this will hlp uh
