5 0

Answer:

6 molecules of Oxygen

Explanation:

From the question ,

Sugar has a molecular formula of C₆H₁₂O₆ .

Hence ,

Using the mole concept , i.e. ,

1 molecule of Sugar , i.e. , C₆H₁₂O₆ has , 6 molecules of Carbon , 12 molecules of Hydrogen and 6 molecules of Oxygen .

Therefore ,

6 molecules of Oxygen is present in 1 molecule of sugar , i.e. , C₆H₁₂O₆ .

A sample of sodium hydroxide (NaOH) has a mass of 160. 0 g. The molar mass of NaOH is 40. 00 g/mol. How many moles of NaOH does

Andrew [12]

4 moles of NaOH is present in the given 160 grams of NaOH.

<h3>How we calculate moles?</h3>

Moles of any substance will be calculated as:

n = W/M, where

W = given mass of NaOH = 160 grams (given)

M = molar mass of NaOH = 40 g/mole

Moles of NaOH is calculated as:

n = 160g / 40g/mol = 4 moles

Hence, moles of sodium hydroxide (NaOH) is 4 moles.

You have 627 ml of 5.04 M HCl. Using a volumetric pipet, you take 229 ml of that solution and dilute it to 921 ml in a volumetri

trasher [3.6K]

Answer:

0.653

Explanation:

M1V1 = M2V2

M1 = 5.04 M

V1 = 229 mL ( you take only this volume)

V2 = 921 mL

5.04*229 = M2 * 921

M2 = (5.04*229)/921 Molarity

M1V1 = M2V2

M1 = (5.04*229)/921

V1 = 100 mL

V2= 192 mL

(5.04*229)/921 *100 = M2 * 192

M2 = [(5.04*229)/921 *100]/192 = 0.653 final molarity

When a solid with a mass of 53.78 g is added to 50.0 ml of water in a graduated cylinder, the volume increases to 56.4 ml. Calcu

Bad White [126]

Answer:

<h3>The answer is 8.40 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

volume = final volume of water - initial volume of water

volume = 56.4 - 50 = 6.4 mL

We have

$density = \frac{53.78}{6.4} \\ = 8.403125$

We have the final answer as

Hope this helps you

A piece of silver (Ag) metal weighing 194.3 g is placed in a graduated cylinder containing 242.0 mL of water. The volume of wate

mariarad [96]

Answer: The density of silver metal will be $10.50g/ml[\tex]Explanation:Density is defined as the mass contained per unit volume.[tex]Density=\frac{mass}{Volume}$

Given : Mass of silver = 194.3 grams

Volume of silver= volume of water displaced= $260.5-242.0=18.5mltex]Putting in the values we get:[tex]Density=\frac{194.3g}{18.5ml}=10.50g/ml/tex]Thus density of silver metal will be [tex]10.50g/ml$
