You will need to look up some conversions of gram to lbs
1 gram = 0.00220462262 pounds
1 mL = 0.000264172052 US gallons
and mL to gal
1.035 g / cm^3 x 0.0022 lbs / 1 gram x 1 mL / 0.000264 gal
You could ask whether the black crust is a new substance formed from silver underwent a chemical change because a chemical change produces a new substance.
Answer:
284.48 g/mol
Explanation:
You can find the molar mass of any molecule by looking at a periodic table and adding up all of the masses of each element. When you do this with stearic acid, you get somewhere around 284.5 g/mol. Hope this helped!
2.79 mol of MnSiO3
This will be very close but may not be exactly accurate, depending on what your periodic table says.
