lana [24]3 years ago
3 0

Answer:

the mass of 8.03 mole of NH3 is 136.51 g

Explanation:

The computation of the mass is shown below:

As we know that

Mass = number of moles × molar mass

= 8.03 mol  × 17 g/mol

= 136.51 g

Hence, the mass of 8.03 mole of NH3 is 136.51 g

We simply multiplied the number of moles with the molar mass so that the mass could come

An unknown liquid has a mass of 30.8 g, and a volume of 31.5 mL. What is the density of this liquid?
julsineya [31]

The density of the liquid is 0.98 g/mL

<h3>What is density? </h3>

The density of a substance is defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as:

Density = mass / volume

With the above formula, we can obtain the density of the liquid.

<h3>How to determine the density </h3>
  • Mass = 30.8 g
  • Volume = 31.5 mL
  • Density =?

Density = mass / volume

Density of liquid = 30.8 / 31.5

Density of liquid = 0.98 g/mL
