Flauer [41]2 years ago

Hey there!

Na + O₂ → Na₂O

Balance O.

2 on the left, 1 on the right. Add a coefficient of 2 in front of Na₂O.

Na + O₂ → 2Na₂O

Balance Na.

1 on the left, 4 on the right. Add a coefficient of 4 in front of Na.

4Na + O₂ → 2Na₂O

Our final balanced equation: 4Na + O₂ → 2Na₂O

Hope this helps!

How much volume would a 834.01g pile of sugar have given that it has a density of 1.59g/mL?
boyakko [2]

Answer:

v = 534.5mL

m = 597.15g

Density = 9.23g/mL

Density = 9.125g/mL

Explanation:

Density = mass/ volume

For the first question

Density = 1.59g/mL

Mass = 834.01g

Volume = ?

Using the above formula we have 1.59 = 834.01/v

v = 834.01/1.59

v = 534.5mL

For the second question

Density =0.9167g/mL

Volume = 651.41mL

Mass =?

Using the above formula we have

0.9167 =m/651.41

Cross multiply

m = 0.9167 x 651.41

m = 597.15g

For the third question

Mass =803.44g

Volume=87.03mL

Density =?

Density = 803.44/87.03

= 9.23g/mL

For the fourth

Density = 56.85/6.23

= 9.125g/mL
