The molar mass of nitrogen (n2) is 28.02 g/mol. what is the mass, in grams, of 4.60 mol of n2?

128.9 grams

Explanation: The moles of the substance is calculated by the expression :

Given :

Molar Mass of = 28.02 g/mol

moles of = 4.60

Putting in the values, we get

given mass= 128.9 grams

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

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).
