How many grams are in 3.7 moles of NA2O?

1 answer:

6 0

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

the volume of a cylinder is given by the formula v=3.14r^2h, where r is the radius of the cylinder and h is the height. suppose

photoshop1234 [79]

we know that

The volume of a cylinder is given by the formula

$V=3.14 r^{2} h$

where

r is the radius of the cylinder

h is the height of the cylinder

in this problem

$r=x+8\\h=2x+3$

Substitute the values in the formula above

$V=3.14*(x+8)^{2}*(2x+3)$

$V=3.14*(x^{2}+16x+64)*(2x+3) \\ V=3.14 *(2x^{3} +3x^{2} +32x^{2} +48x+128x+192)\\ V=3.14*(2x^{3} +35x^{2} +176x+192)$

therefore

<u>the answer is</u>

The volume of the can is equal to

$V=3.14 *(2x^{3} +35x^{2} +176x+192)\ units ^{3}$
