Answer:

Moles of HCl is 0.015.

Explanation:

Molarity of HCl = 0.10 M

Volume of HCl = 150 mL

Conversion factor for mL to L is,

1\ mL = 10^{-3}\ L

So, 150 mL = 0.15 L

Molarity is given by,

Molarity=\frac{Moles}{Volume\ in\ L} \\Moles = Molarity \times Volume\ in\ L

Substitute values in the above formula

Moles = 0.10 \times 0.15\\=0.015\ mol

Moles of HCl is 0.015.

M=mol/liter
We know that we have 150ml=.15 L and .1 mol of HCl
Rearranging the molarity equation, we get
mol=M*l
mol=(.15)(.1)
=.015 mol

The molar madd of Ca(OH)2
Nonamiya [84]
What you have to do is find a periodic table and add the mass of each atom that the compound is made of.

Ca= 40.1
O= 16.0
H= 1.01

keep in mind that you have to also account for how many atoms of each there are in the molecule. for example, in Ca(OH)2, there are one Ca, two O and two H

so the molar mass of Ca(OH)2= 40.1 + (2 x 16.0) + (2 x 1.01)= 74.12 g/mol

A slice of Swiss cheese contains 48 mg of sodium
Nookie1986 [14]

Answer: grams=0.048g, ounces=0.0017oz, 0.00011lb

Explanation:

Stoichiometry

48 mg x  1 g

          ÷  1000 mg  = 0.048 g

48 mg x  1 g            x 16 oz        

          ÷ 1000 mg  ÷ 453.6 g     = 0.0017 oz

48 mg x  1 g            x 1 lb        

          ÷ 1000 mg  ÷ 453.6 g     = 0.00011 lb

How many moles of Cu do you need to react with 12 moles of O2?<br> 2Cu(s) + O2(g) 2CuO(s)
zzz [600]

Answer:

24 mol Cu

General Formulas and Concepts:

<u>Chemistry</u>

  • Stoichiometry

Explanation:

<u>Step 1: Define</u>

RxN: 2Cu (s) + O₂ (g) → 2CuO (s)

Given: 12 moles O₂

<u>Step 2: Stoichiometry</u>

<u />12 \ mol \ O_2(\frac{2 \ mol \ Cu}{1 \ mol \ O_2} ) = 24 mol Cu

<u>Step 3: Check</u>

<em>We are given 2 sig figs.</em>

Our final answer is in 2 sig figs, so no need to round.
