Question

Calculate the mass of a liquid with a density of 4.5 g/mL and a volume of 18 mL

Answer 1

Answer:

81 grams .

Explanation:

Density = Mass / volume

4.5 g/ml = Mass of liquid / volume of liquid

4.5 g/ml = Mass of liquid / 18 ml

Therefore, Mass of liquid is 18× 4.5 = 81 gram.

Answer 2

Answer:

Given :-

• A liquid with a density of 4.5 g/mL and a volume of 18 mL.

To Find :-

• What is the mass of a liquid.

Formula Used :-

$\clubsuit$ Density Formula :

$\bigstar \: \: \sf\boxed{\bold{\pink{\rho =\: \dfrac{m}{v}}}}\: \: \: \bigstar$

where,

• ρ = Density
• m = Mass
• v = Volume

Solution :-

Given :

• Density = 4.5 g/mL
• Volume = 18 mL

According to the question by using the formula we get,

$\implies \sf\bold{\purple{\rho =\: \dfrac{m}{v}}}$

$\implies \bf Density =\: \dfrac{Mass}{Volume}$

$\implies \sf 4.5 =\: \dfrac{Mass}{18}$

By doing cross multiplication we get,

$\implies \sf Mass =\: (4.5)(18)$

$\implies \sf Mass =\: (4.5 \times 18)$

$\implies \sf Mass =\: (81)$

$\implies \sf\bold{\red{Mass =\: 81\: g}}$

$\therefore$ The mass of a liquid is 81 grams .
