Answer:
<h3>The answer is 2.70 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 4.86 g
volume = final volume of water - initial volume of water
volume = 17.3 - 15.5 = 1.8 mL
So we have
We have the final answer as
<h3>2.70 g/mL</h3>

The molar volume of a gas at STP occupies <u>22.4 L.</u>
Option D
<u>Explanation:</u>
To find the volume of 1 mole of a gas at STP, we use the Ideal Gas Law. It is the general gas equation which gives the relation to the measurable quantities to an ideal gas as below,
P (pressure) × V (volume) = n (number of moles) × R (the gas constant) × T (temperature in Kelvin)
STP = 1 atm of pressure and 273 K for temperature
P = 1 atm
V = ?
n = 1 mole
R = 0.0821 atm L/mol K
T = 273 K
Using the equation,
By substituting the above values, in the equation,
V = 22.38 L
