14.2 grams of Na2SO4 is dissolved in water to make a 2.50 L

Trava [24]

Answer:

0.04 M

Explanation:

Given data:

Mass of Na₂SO₄= 14.2 g

Volume of solution = 2.50 L

Molarity of solution = ?

Solution:

Number of moles of Na₂SO₄:

Number of moles = mass/ molar mass

Number of moles = 14.2 g/ 142.04 g/mol

Number of moles = 0.1 mol

Molarity :

Molarity = number of moles of solute / volume of solution in L

Molarity = 0.1 mol / 2.50 L

Molarity = 0.04 M

If an object has an acceleration of 9.8 m/s and a force of 58.8N what is the mass of an object ? What could the object be

Makovka662 [10]

Answer:

The mass of an object is 0.6122 Kg

Explanation:

Given:

Acceleration = 9.8 m/s

Force = 58.8 N

To Find:

Mass of an object = ?

Solution:

We know that according to newtons 2nd law

Force is the product of the mass and acceleration

F= ma

where

F = Force

m = mass

a = Acceleration

Substituting the values,

58.8 = m X 9.8

$m= \frac{58.8}{9.8}$

m = 0.6122 kg
