Answer:

<h2>63.94 cm³</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{50}{0.785}  \\  = 63.694267...

We have the final answer as

<h3>63.94 cm³</h3>

Hope this helps you

How many atoms are in 3.2 moles of chromium?
-BARSIC- [3]

Hey there!

1 mole has 6.022 x 10²³ atoms.

Multiply that by 3.2 because we have 3.2 moles.

3.2 x 6.022 x 10²³

1.9 x 10²⁴

There are 1.9 x 10²⁴ atoms in 3.2 moles of chromium.

Hope this helps!

1. The volume of a gas is 10.0 liters and its temperature is 1500 K. If the temperature is
cupoosta [38]

Answer:

5 L

Explanation:

So this problem refers to Charles's law. You would use this formula..

\frac{V_{I} }{T_{I} }  = \frac{V_{F} }{T_{F} }   (Initial volume / Initial Temperature) = (Final volume / Final Temperature)

For your problem, it would look like this...

\frac{10L}{1500k} = \frac{V_{F} }{750k}

You would cross multiply and your answer would be 5L.

To reassure yourself that the answer is correct, Charles law states that the Volume and the Temperature are directly proportional. Meaning if your temperature is decreasing, your volume <u>has</u> to decrease.

How many moles are in 442.8 g of strontium carbonate (SrCO3)?
GuDViN [60]

Answer:

3 moles

Explanation:

SrCO3

Mass = 442.8g

Molar mass = (87.6 + 12 * [16*3]) = 147.6g/mol

Number of moles = mass / molar mass

Number of moles = 442.8 / 147.6

Number of moles = 3
