To find mass we use the formula Mass = moles x RFM: Mass = 0.560 x 180 = 100.8g of C₉H₈O₄
Hope that helps :)
The largest number of molecules is the same as the largest number of moles of this molecules
to calculate the number of moles you have to divide the mass by the molar mass
molar masses:
CO2: 44,01 g/mol
CH4: 16,04 g/mol
CBr4: 331,63 g/mol
CHBr3: 252,73 g/mol
largest nº of mol= 100/(the smallest molar mass possible)
= 100/16,04
=6,23 moles
all other molecules would be smaller than 6,23 moles because the molar mass is so high.
The answer is B : 1<span>00 g of ch4</span>
El Niño = the boy, La Niña = the girl. You can tell from the ending and the first word.
Answer:
0.092 %
Explanation:
The equation of the reaction can be computed as :


recall that; the number of moles = 
By applying the method of enthalpy of combustion for sucrose at the same time changing the time from hours to seconds, we can determine the total energy output.
i.e


Given that the sun supplies about 1.0 kilowatt, to KJ/m² s, we have:

Finally, the percentage of sunlight used to produce sucrose :
= 
= 0.092 %
Answer:
The answer is
<h2>7.0 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of rock = 14 g
volume = 2 cm³
The density of the rock is

We have the final answer as
<h3>7.0 g/cm³</h3>
