Answer:
any two
Explanation:
Gravitation force or gravitational attraction is a force of pulling or attraction that exist between any two bodies that have a mass. Each and every body attract each other with the force of gravity due to their masses.
Every object in this universe having mass and distance attracts every other object.
Answer:
The answer is
<h2>686.01 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 of zinc = 96.08 cm³
density = 7.14 g/cm³
The mass is
mass = 96.08 × 7.14 = 686.0112
We have the final answer as
<h3>686.01 g</h3>
Hope this helps you
Answer: 0.18 M
Explanation:
Initial molarity, M1 = 0.8 M
Initial olume, V1 = 225 ml
Final volume, V2 = 1000 ml
Final Molarity, M2 = M1V1/V2
= 0.8 x 225/1000
= 0.18 M
