Na₂O has a molecular mass of (2 x 23.0) + 16 = 62. One mole of any substance is its molecular mass in grams, so if 1 mole of Na₂O = 62.0-g, then 5 moles would be 310-g ...(62.0g/mol x 5-mol) = 310-g Na₂O

There are 1,500 students in a school. 65% of them are girls. How many girls are there in the school?
Veronika [31]
First you have to multiply 1,500 by 65%.  A way to do that is 1,500 x 65 and then divide by 100.
So 1,500 x 65 is 97,500.
97,500 divided by 100 is 975.
The final answer is that there are 975 girls in the school.

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
hammer [34]

Answer:

<em>x = 59</em>

Step-by-step explanation:

<u>Equations</u>

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

The image shows a four-sided polygon and its four angles measures, thus we sum them all and equate the sum to 360:

x + x + 2x + 3 + 2x + 3 = 360

Simplifying:

6x + 6 = 360

Subtracting 6:

6x = 354

Dividing by 6:

x = 354/6

x = 59
