Hey there !
a) Pb(SO4)2 => <span> lead(II) sulfate
b) </span><span>The molar mass of this compound was calculated from the amount of atoms of each element, with its respective atomic masses
Pb = 207.2 a.m.u
S = 32.065 a.m.u
O = </span><span>15.9994 a.m.u
Therefore:
</span>Pb(SO4)2 = 207.2 + 32.065 * 2 + 15.9994 * 8 => <span>399.3252 g/mol
</span>
hope this helps!
Answer: Blue liquid density = 45 grams/70 mL Density = .64 g/mL Yellow liquid density = 80 grams/ 65mL Density = 1.23 g/mL After the liquids are combined the blue less dense liquid will rise to the top, while the yellow more dense liquid will sinks to the bottom.
<u>Answer:</u> The volume of barium chlorate is 195.65 mL
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:
Given mass of barium chlorate = 25.0 g
Molar mass of barium chlorate = 304.23 g/mol
Molarity of solution = 0.420 mol/L
Volume of solution = ?
Putting values in above equation, we get:
Hence, the volume of barium chlorate is 195.65 mL
Answer:
you would need to multiply 50 times 2 wich is 100 so i beleive its 100
Explanation:
<span>The round trip is 12.5 miles * 2 way = 25 miles. In order to accomplish this in 45 minutes, or 45/60 = 0.75 hours, Tyrone would have to drive at a speed of 25 miles / 0.75 hours = 33.3 miles per hour. If he were to actually be able to drive continuously at this speed without stopping and the prescription pickup were instantaneous, then he would be able to make the round trip in time. However, in the real world this is unlikely to be the case.</span>
