Answer:
The mass of ascorbic acid in 2.87×10−4 mol are 50,5 mg
Explanation:
Molar mass = 176 g/mol
Moles . molar mass = grams.
2,87 x10*-4 m . 176 g/m = 50,5 x10*-3 grams
A human can take one sweet lime and half to cover the daily requirement of vitamin C. =)
Answer:
the answer is 10 times
Explanation:
because it takes 10 times as much energy -3330 j - to melt 10.0 grams of ice.
Answer: the boiling point is = 137.325°C
Explanation:
From the formula: ∆Tb= Kb*m
From the question, Kb= 0.95, m= 27.5, T1= 111.2°C
Substitute into ∆Tb= Kb*m
∆Tb= 0.95*27.5= 26.125
∆Tb= T2-T1
Hence
T2- 111.2=26.125
T2= 26.125+ 111.2= 137.325°C
