Answer:

3 M

Explanation:

Given data

Moles of sodium hydroxide (solute): 5 moles

Volume of solution: 2 liters

We can calculate the molar concentration, or molarity (M), of the solution using the following expression.

M = moles of solute / volume of solution (in liters)

M = 5 moles / 2 L

M = 2.5 M ≈ 3 M (if we round off to 1 significant figure)

If a 60-g object has a volume of 30 cm3, what is its density? 2 g/cm3 0.5 cm3/g 1800 g * cm3 none of the above

jasenka [17]

Answer : The density of an object is, $2g/cm^3$

Solution : Given,

Mass of an object = 60 g

Volume of an object = $30cm^3$

Formula used :

$\text{Density of an object}=\frac{\text{Mass of an object}}{\text{Volume of an object}}$

Now put all the given values in this formula, we get the density of an object.

$\text{Density of an object}=\frac{60g}{30cm^3}=2g/cm^3$

Therefore, the density of an object is, $2g/cm^3$
