What is the density of a liquid if 12.5 ml of the liquid has a density of 9.80 g?
blagie [28]

Answer:

The answer is

<h2>0.784 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

<h3>density =  \frac{mass}{volume}</h3>

From the question

mass of liquid = 9.8 g

volume = 12.5 mL

The density is

density =  \frac{9.8}{12.5}

We have the final answer as

<h3>0.784 g/mL</h3>

Hope this helps you

The volume of a gas collected when the temperature is 11. 0°c and the pressure is 710 mm hg measures 14. 8 ml. What is the calcu
ivolga24 [154]

Answer:

Original: P₁ = 710 mmHg, V₁ = 14.8 mL, T₁ = (273.2 + 11.0) K = 284.2 K

New: P₂ = 370 mmHg, V₂ = ? mL, T₂ = (273.2 + 20.0) K = 293.2 K

Combined gas law: P₁V₁/T₁ = P₂V₂/T₂

Then, V₂ = V₁ × (P₁/P₂) × (T₂/T₁)

Calculated new volume, V₂ = (14.8 mL) × (710/370) × (293.2/284.2) = 29.3 mL
