Determine the mass in grams of each of the following:

Chemistry
1 answer:
nekit [7.7K]3 years ago
3 0
We know, Given mass = Molar mass * Number of moles.

A.) <span>1.25 mol CaF</span>₂

Number of moles = 1.25
Molar mass = 78

So, Mass = 78 * 1.25 = 97.5 g

B.) 3.4 mol (NH₄)₂SO₄

Number of moles = 3.4
Molar mass = 132

Mass = 3.4 * 132 = 448.8 g

Hope this helps!

What is the total number of hydrogen atoms contained in one molecule of (NH4)2C204?
Ber [7]

Answer:

=8 atoms

Explanation:

In (NH4)2C2O4 there are four moles of Hydrogen in the compound (NH4), but there two molecules of (NH4) in this compound.  That's what the 2 in (NH4)2 means, so multiply 4 x 2 = 8.

Hope this helps (:

Find the mass of 3.00 mol of acetic acid, C2H4O2
Alinara [238K]
Molar mass acetic acid:

C₂H₄O₂ = 12 * 2 + 1 * 4 + 16 * 2 = 60.

n = mass / molar mass

3.00 = m / 60.0

m = 3.00 * 60.0

m = 180 g of <span>C₂H₄O₂

hope this helps!</span>

Calculate the molar mass of RbOH
Ghella [55]

Hey there!

RbOH

Rb: 1 x 85.468 = 85.468

O:  1 x 16 = 16

H: 1 x 1.008 = 1.008

------------------------------------

                   102.476

The molar mass of RbOH is 102.476 g/mol.

Hope this helps!

bp’s efforts to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drill
Eduardwww [97]

The British Petroleum (bp's) effort to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of <u>regulatory policy </u>change.

The deepwater horizon drilling rig is a semi-submersible, transportable, floating, flexibly oriented drilling rig that could work in sea depths of up to 10,000 feet which is approximately 3,000 meters.

During the explosion that occurred in April 2010, British Petroleum made several efforts to contain the damages made and to prevent further outbreaks of disasters.

Part of the changes was shifting from a blowout preventer that has a specialized valve to seal, manage, and monitor oil and gas wells in order to prevent blowouts to a containment dome (a crucial component of a system meant to control an oil well's underwater blowout).

Therefore, we can conclude that the British Petroleum (bp's) effort to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of <u>regulatory policy </u>change.
