Molarity = mol/L
0.175 mol
0.15 L (1000 mL = 1 L)
Molarity = 0.175 mol/0.15 L = 1.1666667 M
An acid can be defined as a proton donor.
Answer:
[K₂CrO₄] → 8.1×10⁻⁵ M
Explanation:
First of all, you may know that if you dilute, molarity must decrease.
In the first solution we need to calculate the mmoles:
M = mmol/mL
mL . M = mmol
0.0027 mmol/mL . 3mL = 0.0081 mmoles
These mmoles of potassium chromate are in 3 mL but, it stays in 100 mL too.
New molarity is:
0.0081 mmoles / 100mL = 8.1×10⁻⁵ M
Answer:
lava is coming from the crust
Explanation:
volcano's explode with lava because the crust pushes it out
