Using the law of dilution :
Mi x Vi = Mf x Vf
2.00 x Vi = 0.15 x 100.0
2.00 x Vi = 15
Vi = 15 / 2.00
Vi = 7.5 mL
hope this helps!
41.6g/cm3 would be the density of the bread
Answer:
b) 99 kPa
Explanation:
According to Daltons law of partial pressure, the total pressure of a mixture of two or more non reactive gases is the sum of their individual pressures. Let the total pressure of a mixture of n number of gases be
and their individual pressure be
, According to Daltons partial pressure law:

Since A glass cylinder contains 2 gases at a pressure of 106 kPa, therefore n = 2. Also one gas (
) is at 7 kPa. Using Daltons partial pressure law:

Liquid is water or drink and solid is hard
