What is the volume of 27 g of aluminum?
If you know the density of aluminum, you can determine the volume of a specific mass of aluminum. Aluminum has a density of 2.70g/cm3. Density = mass/volume. If we know any two variables, we can manipulate the density equation to find the third variable. In this case, we know mass and density, so to find the volume, do the following calculation: Volume = mass/density Volume Al = (27g Al)/(2.70g/cm3 Al) = 10cm3 Al. So, 27g of Al has a volume of 10cm3. * * This answer should technically have two significant figures. As written, it only has one, because trailing zeroes without a decimal are not significant. We can indicate two significant figures by writing it in scientific notation as 1.0 x 101cm3, or we can write it with a decimal as 10. cm3.
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
What is the mass of 136 mL of Mercury?
If you know the density of mercury, you can determine the mass of a specific volume of mercury. Mercury has a density of 13.534g/cm3. 1cm3 = 1mL, so we can restate its density as 13.534g/mL. Density = mass/volume. If we know any two variables, we can manipulate the density equation to find the third variable. In this case, we know volume and density, so to find the mass, do the following calculation: Mass = density x volume Mass Hg = 13.534g/mL x 136mL = 1.84g Hg* *The answer is limited to 3 significant figures, because 136mL has only 3 significant figures, even though the density has 5 significant figures. When multiplying or dividing, the answer is limited to the same number of significant figures as the measurement with the fewest significant figures used in the calculation.
Why is density expressed in two significant figures?
Because density expressed in two significant figures depends on your accuracy of your measurements of mass and volume to calculate as well as any variables that you are expected to use.
Is avogadro's number the same as molar mass?
no youre thinking of molar mass and atomic weight although you use avogadro's number to find molar mass
The molar mass of aluminum chloride is grams?
The molar mass of aluminum chloride (AlCl3) is 133.34 grams/mol.
How many grams are in 5 mole of aluminum chloride?
The molar mass of aluminum chloride (AlCl3) is 133.34 g/mol. To find the mass of 5 moles, you would multiply the molar mass by the number of moles. Therefore, 5 moles of aluminum chloride would be 666.7 grams.
What is the molar mass of aluminum chloride?
The molar mass of aluminum chloride (AlCl3) is 133.34 g/mol. This is calculated by adding the atomic masses of one aluminum atom and three chlorine atoms.
The molar mass of aluminum chloride is?
The molar mass of aluminum chloride (AlCl3) is approximately 133.34 g/mol.
What element has a molar mass of 26.98 grams?
The element with a molar mass of 26.98 grams is aluminum (Al).
The molar mass of NaCO3 to four significant figures is what not inscientific notation?
The formula is either:Na2CO3 (sodium carbonate) with molar mass 105.9884 g/mol (anhydrous),orNaHCO3 (sodium bicarbonate) with molar mass 84.01 g/mol,butNaCO3 doesn't exist.
What is the molar mass of aluminum nitride?
The molar mass of aluminum nitride (AlN) is 40.99 g/mol for aluminum and 14.01 g/mol for nitrogen. Adding these together gives a molar mass of 74.0 g/mol for aluminum nitride.
What is the molar mass of aluminum acetate?
The molar mass of aluminum acetate (Al(C2H3O2)3) is approximately 204.11 g/mol.
What is the mass percent of aluminum in aluminium chlorohydrate?
The mass percent of aluminum in aluminum chlorohydrate is approximately 5-10%. This compound is a group of specific aluminum salts used in antiperspirants and primarily consists of aluminum hydroxide and aluminum chloride.
What is the mass in grams of 1.00 mol Al?
The molar mass of aluminum (Al) is 26.98 g/mol. Therefore, the mass of 1.00 mol of aluminum is 26.98 grams.
What is the molar mass aluminum sulfate?
342.15
The molar mass of aluminum sulfate?
The molar mass of aluminum sulfate, Al2(SO4)3, can be calculated by adding together the atomic masses of all the elements in the compound. Aluminum has a molar mass of 26.98 g/mol, sulfur has a molar mass of 32.06 g/mol, and oxygen has a molar mass of 16.00 g/mol. By calculating the total molar mass, the molar mass of aluminum sulfate is found to be approximately 342.14 g/mol.
