A sample of table sugar (sucrose c12h22o11) has a mass of 3.115 g

1 answer:

6 0

Hey there:

a) atomic mass:

Carbon =<span>12.0107 g/mol

</span>Hydrogen = <span>1.00794 g/mol

Oxygen = </span><span>15.9994 g/mol
</span>
Therefore:

C12H22O11 =

12 * 12.0107 + 1 * 1.00794 + 16 * 15.9994 => <span>342.29648 g/mol

__________________________________________________________

b) number of moles:

n = m / mm

n = 3.115 / </span><span>342.29648

n = 0.0091 moles

hope this helps!</span>

How many moles are contained in 2.3 liters of a 1.2M solution?

elena-s [515]

Answer:

$\boxed {\boxed {\sf 2.76 \ mol}}$

Explanation:

Molarity is found by dividing the moles of solute by liters of solution.

$molarity = \frac {moles}{liters}$

We know the molarity is 1.2 M (mol\liter) and there are 2.3 liters of solution. Substitute the known values into the formula.

$1.2 \ mol/liter= \frac {x}{2.3 \ liters}$

Since we are solving for x, we must isolate the variable. It is being divided by 2.3 and the inverse of division is multiplication. Multiply both sides by 2.3 liters.

$2.3 \ liters *1.2 \ mol/liter= \frac {x}{2.3 \ liters}* 2.3 \ liters\\2.3 *1.2 \ mol= x\\2.76 \ mol =x$

In a solution with a molarity of 1.2 and 2.3 liters of solution, there are 2.76 moles.

What is the charge of a cation?

kolezko [41]

Answer:

A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.

An object has a mass of 3.50 grams and a density of 5.61 g/mL. What is the volume of this object? *

Elina [12.6K]

Answer:

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

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

From the question we have

$volume = \frac{3.50}{5.61} \\ = 0.6238859...$

We have the final answer as

Hope this helps you
