Answer: The molar mass of is 67.81 g/mol
Explanation:
Molar mass is defined as the mass in grams of 1 mole of a substance.
S.I Unit of Molar mass is gram per mole and it is represented as g/mol.
Atomic Mass of Boron (B) = 10.81 g
Atomic Mass of Flourine (F) = 18.99 g
Molecular mass of = 1 (10.81)+3(18.99) g = 67.81 g
Thus molar mass of is 67.81 g/mol
Answer:
80 mL
Explanation:
Step 1: Given data
- Initial pressure of hydrogen (P₁): 360 mmHg
- Initial volume of hydrogen (V₁): 240 mL
- Final pressure of hydrogen (P₂): 1080 mmHg
- Final volume of hydrogen (V₂): ?
Step 2: Calculate the final volume of hydrogen
If we assume ideal behavior and constant temperature, we can calculate the final volume occupied by hydrogen using Boyle's law.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁/P₂
V₂ = 360 mmHg × 240 mL/1080 mmHg = 80 mL
4.7 ft is equal to 55 in.
To find out how many inches are in 4.7 ft, you have to multiply 4x12 because there are 12 in in a ft. Since 4x12=48, just at the 7 in to 48 and you’ll get 55 in.
C because this is not very deep and towards the surface you are more likely to find solid rocks
