Answer:
Option c.
Explanation:
According to Newton's law, formula to solve this problem is:
F = m . a
Mass → 1000 kg
a → 3 m/s²
F = 1000 kg . 3m/s² → 3000 N
1 N = 1 kg . m/s² according to SI, Internation System of units.
Answer:
0.209 mol/L
Explanation:
Given data
- Mass of copper(lI) sulfate (solute): 11.7 g
- Volume of solution: 350 mL = 0.350 L
The molar mass of copper(Il) sulfate is 159.61 g/mol. The moles corresponding to 11.7 grams are:
11.7 g × (1 mol/159.61 g) = 0.0733 mol
The molarity of copper(Il) sulfate is:
M = moles of solute / liters of solution
M = 0.0733 mol / 0.350 L
M = 0.209 mol/L
Answer:
Axis Labels
Explanation:
The axis labels are usually located on the x and y axis. This graph however is missing those.
hope this helps!
Divide by the molar mass of HCl which is 36.5g/mol grams cancels out and you are left with 1.99 mol.
