<span>12810 atomic mass units
Since a monomer is the basic building block of a polymer, we just need to multiply the mass of the monomers by the number of monomers used. So
105 atomic mass units * 122 = 12810 atomic mass units</span>
Answer:
here: "salt and sugar"
Explanation:
I dunno, looks pretty, gives 5 points. even tough any context is missing
but seriously:
salt and sugar look the same. just someone with a split personality
Answer:
45.02 L.
Explanation:
- Firstly, we need to calculate the no. of moles of water vapor.
- n = mass / molar mass = (36.21 g) / (18.0 g/mol) = 2.01 mol.
- We can calculate the volume of knowing that 1.0 mole of a gas at STP occupies 22.4 L.
<em><u>Using cross multiplication:</u></em>
1.0 mole of CO occupies → 22.4 L.
2.01 mole of CO occupies → ??? L.
∴ The volume of water vapor in 36.21 g = (22.4 L)(2.01 mole) / (1.0 mole) = 45.02 L.
First find the number of moles of KSCN is in 4.40g of KSCN
1. Number of moles = mass given (4.40g) / molecular weight(MW) (KSCN)
- to calculate MW, look for each element in the periodic table and add their atomic weight
2. Convert 200mL to liters
3. Concentration = number of moles/ volume in liters from (#2)
Answer:The bubbles exhaled by a scuba diver grow as they approach the surface of the ocean. The pressure exerted by the weight of the water decreases with depth, so the volume of the bubbles increases as they rise.
