Answer:
<h2>18 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

volume = final volume of water - initial volume of water
volume = 62 - 52 = 10 mL
From the question we have

We have the final answer as
<h3>18 g/mL</h3>
Hope this helps you
Answer:
the question is incomplete
Answer:
The mass of an object is 0.6122 Kg
Explanation:
Given:
Acceleration = 9.8 m/s
Force = 58.8 N
To Find:
Mass of an object = ?
Solution:
We know that according to newtons 2nd law
Force is the product of the mass and acceleration
F= ma
where
F = Force
m = mass
a = Acceleration
Substituting the values,
58.8 = m X 9.8

m = 0.6122 kg
Answer: Chemical Reactions
Explanation:
Chemical reactions often involve changes in energy due to the breaking and formation of bonds.
Answer:
molarity = moles of solute/liters of solution
0.25 M NaOH = 0.25 mol NaOH/L
mass = moles (n) × molar mass (M)
n(NaOH) = 0.25 mol
M(NaOH) = 39.997 g/mol
m(NaOH) = 0.25 mol × 39.997 g/mol = 9.999 g
