The heat capacity of aluminum is 0.900 J/g degrees Celsius . How much energy is needed to raise the temperature of a 8.50 x 10^2 g block of aluminum from 22.8 degrees Celsius to 94.6 degrees Celsius
E = m*c*(t2 - t1) = 8.5*10^2*0.9*(94.6 - 22.8) = 54927 J

how many ml of water at 10 degrees celsius (2 significant figures) must be added to 75 ml of water at 35 degrees celsius to obtain a final temperature of 19 degrees celsius?
Q=mCΔT ; where m is the mass of the substance, C is the specific heat of the substance, and ΔT is the difference in temperature.35 -19 = 1619-10 = 916...

a certain quantity of gas occupies 10 liter at 25 degree Celsius and a pressure of 1 atm . at what pressure will the volume of gas be 1 liter
Due to ideal gas law:pV/T = constp1V1/T1 = p2V2/T2p2 = (p1*V1*T2)/(T1*V2) = 10 atm

The average osmotic pressure of blood at 25°C is 7.7 atm. How many grams of glucose (C6H12O6) is needed to prepare a 110L solution that is isotonic with blood at 25°C?
If the solution is isotonic, it means that it has the same osmotic pressure.π=CRTC=π/RTT=25+273=298(K)C=7.7/(0.082×298)=0.315(mol/L)n=C×V=0.315×110=34.65(mol)m=n×MM=6×12+12×1+6×16=180(g/mol)m=34.65×180=6237(g)
