Question 10 What volume is occupied by 1.64 x 1019 atoms of Helium gas at STP?
O 1.22 x 10-6 L He
O 2.21 x 1044 L He
0.000610 L He
O 4.41 x 1041 L He

0.00061L He

Explanation:Avogadro constant, N = 6.02214076*10^23 per mole

at STP 1 mole = 22.71L

1.64*10^19 He = ( 1.64*10^19/N)*22.71 = 1.64*10^19*[3.77*10^-23] = 6.18*10^-4L

answer: a chemical reaction

explanation:

im not wrong

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
