A chemistry student needs 60.0 g of tetrahydrofuran for an experiment. By consulting the CRC Handbook of Chemistry and Physics,
the student discovers that the density of tetrahydrofuran is 0.889g*cm^-3 . Calculate the volume of tetrahydrofuran the student should pour out. Be sure your answer has the correct number of significant digits.
A) the independent variable is the variable that doesn’t rely on another variable. For this question the independent would be the days. b) the dependent variable is the number of bacteria c) ‘Number of bacteria across a number of days’
In photosynthesis ENERGY from light is used to convert CARBONDIOXDE and water into glucose and oxygen for 6 carbon and 6 water molecules, 1 glucosed and 6 oxygen molecules are produced.
To solve this we assume
that the gas inside the balloon is an ideal gas. Then, we can use the ideal gas
equation which is expressed as PV = nRT. At a constant pressure and number of
moles of the gas the ratio T/V is equal to some constant. At another set of
condition of temperature, the constant is still the same. Calculations are as
follows:
