Molar mass HCl = 36.5 g/mol and NaOH = 40.0 g/mol
molarity of NaOH = 1.0 M
Volume of NaOH = 20.00 mL in liters : 20.00 / 1000 = 0.02 L
Number of moles NaOH :
n = M * V
n = 1.0 * 0.02
n = 0.02 moles Of NaOH
Finally Molarity of the <span>acid solution
</span>
Volume HCl : 15.0 mL in liters : 15.0 / 1000 = 0.015 L
1 HCl + 1 NaOH = 1 H₂O + 1 NaCl
1 mole HCl --------- 1 mole NaOH
? mole HCl --------- <span> 0.02 moles NaOH
</span>
moles HCl = 0.02 * 1 / 1
= 0.02 moles of HCl
M ( HCl) = n / V
= 0.02 / 0.015
= 1.333 M of HCl
hope this helps!
Answer:
I think the correct answer is a
Explanation:
that's the only part that could really be used to protect itself,
Each molecule of Sr₃(PO₄)₂ contains 3 moles of Sr
So 3 moles of Sr⁺² ions are in one mole of Sr₃(PO₄)₂.
The answer to this would be green house gas. I believe that Greenhouse Gases contain just about all of the different gases above that you've got as multiple answer choices.
62.3018 g/mol is the molar mass
