How many moles of water, H2O, contain 2.0×1022 molecules of water

andreev551 [17]

Answer:

<h3>The answer is 0.03 moles</h3>

Explanation:

To find the number of moles given the number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

N = 2 × 10²² molecules of water

We have

$n = \frac{2 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.033222591...$

We have the final answer as

<h3>0.03 moles</h3>

Hope this helps you

Pls help!!! Write asap!! <br> How many moles of sulfur are there if you have 0.994g of sulfur

timama [110]

To convert weight to moles, we must use the molar weight found on the periodic table. Sulfur's (S) molar weight is 32.06 g/mol. Then we set up an equation and cancel out units:

$\frac{1mole}{32.06g}*0.994g=0.031mol=3.1*10^{-2}mol$
