Since its volume you do what it says 55 cm x 100 cm x 80cm and do 100 x 50 which is 5,000. then 5,000 x 80 which is 40,000. sorry i cant show work on here.
Answer: 147 mL
Explanation:
<u>Given:</u>
Molarity of the sodium bromide (NaBr) solution (M1) = 1.75 M
Volume of the solution (V1) = 84 mL
Molarity of the diluted NaBr solution (M2) = 1 M
Using the dilution formula to solve for V2:
Therefore, the new volume of the solution is 147 mL
Answer is: three.
Unbalanced chemical reaction: Fe+4H₂O → Fe₃O₄ + 4H₂.
Balanced chemical reaction: 3Fe+4H₂O → Fe₃O₄ + 4H₂.
In balanced reaction, there is three iron atoms on the left and on the right, eight hydrogen atoms and four oxygen atoms on both side of chemical reaction.
That means that one mole of sulfur has a mass of 32.065 grams. b) This compound contains two hydrogen atoms and one oxygen atom. To find the molar mass of H2O, we need to add the mass of two hydrogen atoms plus the mass of one oxygen atom. We get: 2(1.008)+16.00=18.016g/mol.
