Answer:
Her acceleration was 0.8 m/s².
Explanation:
Given data:
Final speed v₂ = 5.4 m/s
Initial speed v₁= 3.0 m/s
Initial time t₁ = 2 s
Final time t₂ = 5 s
Acceleration = ?
Solution:
acceleration = (v₂- v₁) / (t₂ - t₁)
acceleration = 5.4 - 3 / 5-2
acceleration = 2.4 / 3 = 0.8 m/s²
Given : Density of Bromine = 3.12 g/mL
Formula : Density = Mass / Volume
Part A :
Given Volume = 125 mL
Density = Mass / Volume
So, Mass = Density x Volume
= 3.12 x 125
= 390 grams
Part B :
Given mass = 85.0 gm
Density = Mass / Volume
So, Volume = Mass / Density
= 85 / 3.12
= 27.24 mL
Answer:
m= 6.9905 = 7 g
Explanation:
The formula is m= M.n
m= mass (g), M= Molar mass (g/mole), n= moles (moles)
Molar mass of Cu is 63.55
=) m= 63.55*0.11
m= 6.9905 = 7 g
