An organic solvent has a density of 1.31 g/mL. What volume is occupied by 57.5 g of the liquid?

Burka [1]

Answer:

<h3>The answer is 43.89 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question

mass = 57.5 g

density = 1.31 g/mL

We have

$volume = \frac{57.5}{1.31} \\ = 43.89312977...$

We have the final answer as

Hope this helps you

how many moles of an ideal gas would occupy a 25.0 liter container when the temperature is 295 K and the pressure is 0.850 atm?

BlackZzzverrR [31]

Answer:

Required number of moles of ideal gas is 0.877 moles.

Explanation:

Pressure (P) = 0.850 atm

Temperature (T) = 295 K

Volume (V) = 25 ltr

Universal gas constant (R) = 0.0821

no of moles (n) = ?

we have the ideal gas equation as:

PV= nRT

or, 0.850× 25 = n × 0.0821 × 295

or, n = 0.877 moles

Hence the required number of moles of an ideal gas is 0.877 moles.
