HELP ASAP!!! How many grams of lead are in a 41.2 gram sample of lead (II) oxide? With work please :)

1 answer:

5 0

That would be 58.6 oxide because if the 41.2 plus the oxide would be 48 plus the other particcles inside it so it equaled 58.6 oxide

An aqueous solution of 10.03 g of catalase, an enzyme found in the liver, has a volume of 1.05 L at 27°C. The solution's osmotic

-Dominant- [34]

Answer : The molar mass of catalase is, $2.40\times 10^5g/mol$

Explanation :

Formula used :

$\pi =CRT\\\\\pi=\frac{w}{M\times V}RT$

where,

$\pi$ = osmotic pressure = 0.745 torr = 0.000980 atm (1 atm = 760 torr)

C = concentration

R = solution constant = 0.0821 L.atm/mol.K

T = temperature = $27^oC=273+27=300K$

w = mass of catalase = 10.03 g

M = molar mass of catalase = ?

V = volume of solution = 1.05 L

Now put all the given values in the above formula, we get:

$0.000980atm=\frac{10.03g}{M\times 1.05L}\times (0.0821L.atm/mole.K)\times (300K)$

$M=2.40\times 10^5g/mol$

Therefore, the molar mass of catalase is, $2.40\times 10^5g/mol$
