Atom is the correct answer i believe
One mole of carbon atoms has a mass of exactly 12 g. Because magnesium atoms each have twice the mass of carbon atoms (24Mg compared with 12C), one mole of magnesium has a mass of 24 g. In fact, one mole of any element has a mass in grams that is equal to its relative atomic mass. One mole of iron has a mass of 56 g
Answer:
0.109 M
Explanation:
change the 974 mL to L (0.974L)
17g x molar mass (159.6g/mol)/0.974=0.109 M
The answer is A. How does the cuddle fish change its colors ?
Answer:
a) 4480L
b) 56L
Explanation:
To answer this question you need to know that Cl2 molecular weight is 71 g/mol and gas volume at NTP is 22.4 L/mol.
a) 14.2 kg of Cl2 in moles will be: 14.2 kg * (1000g/kg) / ( 71g/mol)= 200 mol
The volume of 200 mol of gas in NTP will be: 200 mol * 22.4L/mol= 4480L
b) every mol is made of 6.02 * 10²³ molecules. Then the volume of the gas will be: (15,055×10²³ molecule) / (6.02 * 10²³ molecules/mol) * 22.4 L/mol= 56L
