<h3>Answer:</h3>

1.265 g/mL

<h3>Explanation:</h3>

<u>We are given;</u>

  • Mass of a rock as 43 g
  • Volume of the rock as 34 mL
  • Altitude of the rock as 4390 ft

We are required to calculate the density of the rock.

Density is the mass of an object per unit volume.

It is calculated by;

Density = Mass / volume

Therefore;

Density = 43 g ÷ 34 mL

             = 1.265 g/mL

Thus, the density of the rock is 1.265 g/mL

Ymorist [56]

Answer: -

2.5 mL

Explanation: -

Volume of final solution = 10 mL

Strength of final solution = 10 mg / mL

Amount of drug required = Volume of final solution x strength of final solution

= 10 mL x 10 mg/ mL

= 100 mg.

Strength of supplied drug = 40mg/ mL

Volume of supplied drug required = \frac{100 mg}{40 mg/ mL}

= 2.5 mL

Thus to make 10 ml of a 10 mg/ml solution. 2.5 mL will be needed.
