The gas pressure inside a high vacuum chamber is 0.000000132atm. Calculate the gas pressure in mmHg and torr. Round each of your

Bumek [7]

Answer:

The gas pressure in both mmHg and torr is 1.00 x10⁻⁴.

Explanation:

The standard atmosphere (1 atm) equals a pressure of 760 mmHg, where mmHg represents the pressure exerted by a column of mercury 1 mm high. <u>The mmHg unit is also called the torr</u>, after the Italian scientist Evangelista Torricelli, who invented the barometer. Thus,

1 torr = 1 mmHg

and

1 atm = 760 mmHg = 760 torr

Therefore, we do the following conversion:

1 atm ------------------- 760 mmHg

1.32x10⁻⁷ atm ------- x= 1.00 x10⁻⁴ mmHg (3 significant digits)

Constance has an apple that weighs 85,000 milligrams and a peach that weighs 0.15 kilograms. which fruit has the greater mass? c

Rama09 [41]

The fruit which has the greater mass is peach i.e. 150 grams.

Mass is a quantity which is used to define that what amount of substance will occupy any space or present in the given object.

We have given,

Weight of apples = 85,000 mg

Weight of peach = 0.15 kg

To compare the quantity first we have to convert both of these units in the same unit, and we know that:

In 1 kilogram = 1000 grams

And in 1 grams = 1000 milligrams

So, we convert both the units into grams as:

85,000 mg = 85,000 / 1000 = 85 grams

0.15 kg = 150 grams

So, the mass of peach is high.

Hence, peach has the greater mass.

During an experiment, 321.1 grams of strontium phosphite are measured into a beaker. How many moles of strontium phosphite are i

Allushta [10]

321.1 g of strontium phosphite will contain 0.76 moles of strontium phosphite in the beaker.

<u>Explanation:</u>

It is known that 1 mole of any substance is equal to the molar mass of that substance. So for the case of strontium phosphite, the molar mass is found to be 420.8 g/mol.

This means 1 mole of Strontium phosphite will contain 420.8 g of strontium phosphite.

Then 1 g of strontium phosphite will have $\frac{1}{420.8}$ moles of strontium phosphite.

So, 321.1 g of strontium phosphite will contain $\frac{321.1}{420.8}=0.76 moles$

Thus, 321.1 g of strontium phosphite will contain 0.76 moles of strontium phosphite in the beaker.
