Answer:
0.32 grams
Explanation:
To go from moles to grams (I assume you meant mass instead of weight) you start by finding the molar mass. For O2, the molar mass is 32, because there are two oxygen atoms so 16 grams multiplied by 2.
After that, you take your given moles and multiply it by the grams per mole. The moles cancel each other out and you get your value in grams. I have attached my work below.
Hope this helps! :^)
Answer:
x = 5 kg
Explanation:
Given data:
Number of bushel = 0.20
Mass of 0.20 bushel apples = 2 kg
Mass of 0.50 bushel apples = ?
Solution:
The given problem will solve by cross multiplication.
0.20/ 2.0 = 0.50 / x
x = 2/0.20 × 0.50
x = 10 × 0.50
x = 5 kg
The electron is the has the negative charge, the protón positive and neutron neutral.
Answer:
1.12x10²³ atoms of F
Explanation:
A molecule is a group of 2 or 3 atoms that are bonded by electrostatic charges.
In 1 molecule of MgF2 there are 2 atoms of fluorine and 1 atom of magnesium.
Thus, there are 2 atoms of fluorine per molecule of MgF2. In 5.6x10²² molecules:
5.6x10²² molecules MgF2 * (2 atoms Fluorine / 1 molecule MgF2) =
<h3>1.12x10²³ atoms of F</h3>
Option B is correct
K = Kp /Kr
The given equation indicating, the product containing 6 moles of proton whereas the reactant contains 2 mole of bismuth and 3 mole of hydrogen sulphide.
Hence, in reaction B there are 2 mole of bismuth and 3 mole of hydrogen sulphide reacting to produce 6 moles of proton. whereas the concentration of Bi2S3 is not considered as it is present in solid phase.
