Find the volume of 200g of benzene, if the density of benzene is 0.88 g/mL.
Lina20 [59]

Answer:

<h2>227.27 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question we have

volume =  \frac{200}{0.88}  \\  = 227.2727...

We have the final answer as

<h3>227.27 mL</h3>

Fill in the coefficients that will balance the following reaction: <br> Zn +Fe(NO3)2---ZnNO3+Fe
kakasveta [241]
In order to balance reactions, the number of each element must be the same on the left and right side. If I have 3 of element X on one side, I must have 3 of element X on the other side. That being said:

Zn + Fe(NO3)2 —> ZnNO3 + Fe

I have two NO3 groups on the left, so I will add a coefficient of 2 in front of the compound which has an NO3 group on the right side.

Zn + Fe(NO3)2 —> 2ZnNO3 + Fe

Since I now have 2 Zn’s on the right, and only 1 on the left, I will add a coefficient of 2 in front of Zn on the left.

2Zn + Fe(NO3)2 —> 2ZnNO3 + Fe

Lets check:
Zn: 2 right, 2 left (correct)
Fe: 1 right, 1 left (correct)
NO3 groups: 2 right, 2 left

We have successfully balanced the equation. :)
