Answer:
<h2>The answer is 0.5 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 5 cm³
density = 0.1 g/cm³
The mass is
mass = 0.1 × 5
We have the final answer as
<h3>0.5 g</h3>

Answer:
The number of moles in 80 g of O2 = 3280 = 2.5.
Explanation:
Trust me ._.
Given:
8.32 J of heat
from 23.2 degrees C to 30.5
degrees C
heat capacity of aluminum is 0.90 J/g-K
Required:
m in grams
Solution:
H
= mCpT
(8.32 J) = m(0.90 J/g-K)(30.5 – 23.2)K
m = 1.27g
