The lung capacity of the blue whale is 4900 L . Convert this volume into gallons
adell [148]
1 liter = 2.11 pints
8 pints = 1 gallon

4900 L * (2.11 pints/1 L) * (1 gallon/8 pints) = 1292.375 gallons

4900 has 2 significant figures, so our final answer should have two. Your final answer is 1300 gallons.

What heat is liberated in the formation of 10.0 grams of sulfur hexafluoride, SF6, from the elements sulfur and fluorine?
tensa zangetsu [6.8K]

Answer:

Q=-76.7kJ

Explanation:

Hello,

In this case, for such formation of sulfur hexafluoride, the standard enthalpy of formation is -1220.47 kJ/mol (data extracted from NIST database). Next, we compute the moles in 10.0 grams of sulfur hexafluoride as shown below:

n_{SF_6}=10.0gSF_6*\frac{1molSF_6}{146.06 gSF_6}=0.0685mol

Next, for the given energy, we compute the total heat that is liberated:

Q=-1220.47\frac{kJ}{mol}*0.0685 mol\\\\Q=-76.7kJ

Finally, we conclude such symbol has sense since negative heat is related with liberated heat.

Best regards.

Saltpeter is a compound made of potassium (k), nitrogen (n), and oxygen (o). every 100.00 g of saltpeter contains 38.67 g potass
xeze [42]
First, we need to compute the mass of oxygen found in 100 grams of saltpeter:
mass of oxygen = 100 - (mass of potassium + mass of nitrogen)
                          = 100 - (38.67 + 13.86)
                          = 100 - 52.53
mass of oxygen in 100 grams saltpeter = 47.47 grams

Now, we can use cross multiplication to find the mass of oxygen in 328 grams saltpeter as follows:
mass of oxygen = (328 x 47.47) / 100 = 155.7016 grams
