To get density, you divide mass by volume. You get 3.2954.
1 mole contains 6.02 * 10^23 molecules
0.578 moles of water contains 0.578 * 6.02 * 10^23 molecules
Answer:
<h2>15 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
3000 g = 3 kg
We have
net force = 3 × 5 = 15
We have the final answer as
<h3>15 N</h3>
Hope this helps you
Answer:
<h3>The answer is 13.87 g</h3>
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
density of metal = 5.78 g/mL
volume = final volume of water - initial volume of water
volume = 24.7 - 22.3 = 2.4 mL
We have
mass = 5.78 × 2.4 = 13.872
We have the final answer as
<h3>13.87 g</h3>
