Suppose that 7.25 x 10^22 atoms of a hypothetical element have a mass of 3.88 g. What would be the molar mass (g/mol) of this el
S_A_V [24]

Answer:

32.23 to 4 significant figures.

Explanation:

The molar mass of the element is the mass of 6.022 * 10^23 atoms (Avogadro's number).

So by proportion it is 6.022 * 10^23 * 3.88 / 7.25 * 10^22

= 32.23 to 4 significant figures.

At a fixed pressure, if the temperature is doubled, the volume of a gas will be
Scrat [10]

Answer:

Doubled.

Explanation:

The relationship between the temperature and the volume of a gas at a constant pressure can be described using Charles' law:

  • V₁*T₂ = V₂*T₁

That means that the temperature and the volume of a gas are directly proportional: The higher the temperature, the higher the pressure. If one of those factors is increased twofold, the other one will be increased twofold as well.
