6 moles to equal that I do t know for sure though
Answer:
0.31 mole
Explanation:
The following data were obtained from the question:
Mass of SF6 = 45.0 g
Number of mole of SF6 =..?
Next, we shall determine the molar mass of SF6.
This can be obtained as follow:
Molar mass of SF6 = 32 + (19×6)
Molar mass of SF6 = 32 + 114
Molar mass of SF6 = 146 g/mol
Finally, we shall determine the number of mole in 45 g of SF6 as follow:
Molar mass of SF6 = 146 g/mol
Mass of SF6 = 45.0 g
Number of mole of SF6 =..?
Number of mole = mass /Molar mass
Number of mole of SF6 = 45 /146
Number of mole of SF6 = 0.31 mol
Therefore, 0.31 mol is present in 45 g of SF6.
Answer:
Increasing the temperature of a system will increase the rate of a reaction. More particles are moving faster, and have more energy, increasing the overall rate of reaction.

I hope this helps :)
Just took the test and it was 32grams. On my test it was Block B: 32 Grams
Answer:
79.90amu
Explanation:
To calculate the average atomic mass of an bromine we must multiply the masses of its isotopes with the percent abundance divided by 100. Then you add them together for your answer.
50.69 ÷ 100 = 0.5069
49.31 ÷ 100 = 0.4931
78.9183361amu × 0.5069 = 40.00amu
80.916289amu × 0.4931 = 39.90amu
40.00amu + 39.90amu = 79.90amu
