I need to determine the required flow rate to attain 2.0 resolution from a plot drawn between flow rate and resolution.
The 2.0 resolution is not in the range of plot

How much heat is lost when a 56g glass of 80 °C water cools down to 0 °C.

A fuel contains 4% hydrogen; 89% carbon; 1% sulphur; 2,5% oxygen, 3,5% ash and 20% excess air is supplies

Calculate

1.1 The mass of oxygen required to complete combustion of 1kg of fuel

Equal volumes of oxygen and nitrogen were allowed to diffuse under the similar conditions of temperature and pressure.If oxygen took 18s to diffuse , determine the time that would be taken by nitrogen

1.A fixed mass of gas has 248cm³ at temperature of _20degress and 760mmHg pressure. Calculate the temperature in degree celicius the has would occupy 458cm³ at 780mmHg pressure
2.carbon (iv)oxide takes 200s to diffuse through a porous . How long will it take for the same amount of carbon (iv)oxide to diffuse through the plug under the same condition
3.A gas occupies a volume of 13dm³ at 15degress celcius and 760mm of mercury pressure.What volume would it occupy at stp and pressure
3.Thr pressure exerted by a gas in a sealed container is 1000kpa at 17degress .It was found that the container might leak if the internal pressure exceeds 1200kpa.Assuming constant volume,at what temp in degree will the container start to leak

1.A gas occupies a volume of 400cm³ at 500k and atmosphere pressure.what will be the temperature of the gas when the volume and pressure of the gas is 100cm³ and 0.5atomsphere respectively
2.Gas A takes 10sec to diffuse through a distance of one fifth of a meter.Another gas B takes the same time to diffuse through a distance of 10cm.If the rfm of gas A is 60, calculate the molecular mass of gas B
