Calculate the mass of Sb produced when 0.122 moles of is produced. Show work.
nikdorinn [45]

Answer:

14.9 g Sb

Explanation:

The mass of Sb produced can be calculated using the conversion:

Molar Mass (g/mol) = mass (g) / moles

Antimony (Sb) has the molar mass 121.76 g/mol. This value is found on the periodic table. You have been given the moles produced. Therefore, you can find the mass of Sb by plugging these values into the formula and simplifying.

Molar Mass = mass / moles

121.76 g/mol = mass / 0.122 moles

14.9 = mass

How much force is needed to accelerate a 1000-kg car at a rate of 3 m/s2? a 1003 N b 0.003 N c 3000 N d 333.3 N
Bogdan [553]

Answer:

Option c.

Explanation:

According to Newton's law, formula to solve this problem is:

F = m . a

Mass → 1000 kg

a → 3 m/s²

F = 1000 kg . 3m/s² →  3000 N

1 N = 1 kg .  m/s²  according to SI, Internation System of units.

How many molecules of ammonia are contained in 10.4 moles of ammonia, NH3?
seraphim [82]
Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We do as follows:

10 mol NH3 ( 6.022 x 10^23 molecules / 1 mol ) = 6.022x10^24 molecules NH3
