Answer:
The answer is
<h2>6.0 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
density = 2.7 g/mL
mass of aluminum = 16.2 g
The volume is
We have the final answer as
<h3>6.0 mL</h3>
Hope this helps you
Answer:
V = 44.85 L
Explanation:
Given data:
Volume of H₂ = ?
Number of moles of H₂ = 2.0 mol
Given temperature = 273.15 K
Given pressure = 1 atm
Solution:
Formula:
PV = nRT
P = Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
By putting values,
1 atm × V = 2.0 mol × 0.0821 atm.L/ mol.K × 273.15 K
V = 44.85 atm.L / 1 atm
V = 44.85 L
C is your answer. Because if you add two of them together you get a compound.
