Answer: 30.978
Explanation:
From the equation 2 moles of Fe will result in 3 moles copper
so .325 moles Fe will result in .4875 moles Cu
Cu weights 63.546 gm per mole
.4875 moles * 63.546 gm / mole = 30.978 gm of Cu
Answer:
By a resource or an EXTREMELY good explanation with good reasons and details.
Explanation:
The hills and valleys decrease the height and speed of the ride. This means that the graph has a negative correlation.
By the way, I think you may have plotted your points incorrectly. The directions said to connect them all with a smooth line or curve.
Also, this is not high school chemistry. This is more likely to be elementary school science. Just make sure that you put your questions in the correct categories next time! :)
Answer:
There are 0.0267 moles of oxygen in 0.658 grams of magnesium nitrate.
Explanation:
Mass of magnesium nitrate = m = 0.658 g
Molar mass of magnesium nitrate = M = 148 g/mol
Moles of magnesium nitrate = n
1 mole of magnesium nitrate has 6 moles of oxygen atoms. Then 0.004446 moles magnesium nitrate will have :
There are 0.0267 moles of oxygen in 0.658 grams of magnesium nitrate.
