What is the boiling point of a solution of 0.10 mole of glucose in 200ml of water?
To determine the boiling point of a solution of glucose in water, we first calculate the molality of the solution. With 0.10 moles of glucose in 200 mL of water (approximately 0.2 kg), the molality is 0.5 mol/kg. The boiling point elevation can be calculated using the formula ΔT_b = i * K_b * m, where K_b for water is 0.512 °C kg/mol. Thus, the boiling point elevation is approximately 0.26 °C, raising the boiling point of water from 100 °C to about 100.26 °C.
The density of a liquid whose boiling point is 55 to 57 c was determined to be 0.77 plus - 0.05 gml what is the liquid?
The density of the liquid, 0.77 ± 0.05 g/mL, along with its boiling point range of 55 to 57 °C, suggests that it is likely to be a light hydrocarbon or an organic solvent. A common candidate that fits these criteria is ethyl acetate, which has a boiling point of about 77 °C and a density around 0.9 g/mL. However, if we consider the lower boiling point range, another possible liquid could be pentane, which has a boiling point of about 36 °C and a density close to 0.63 g/mL. Ultimately, more context or specific data may be needed for precise identification.
Which has more mass 19.3 ml of water or 1.00 ml of gold?
One litre of water equals one kilogram of water
What is the volume of the water in a 8 ml Graduated cylinder?
A milliliter is comparable to one cubic centimeter, so if you have 8 ml of water, you have 8 centimeters cubed.

What is the saturation point of caffeine in water at water's boiling point?
The saturation point of caffeine in water at water's boiling point is approximately 66 g per 100 mL of water. This means that at this temperature, water can dissolve up to 66 grams of caffeine per 100 milliliters of water before reaching saturation.

How many mL of boiling water are required to dissolve 25g of phthalic acid?
Phthalic acid will dissolve 18g of per 100mL of boiling water. (25g/18g) x 100mL = 138.89mL of boiling water is needed to dissolve 25g of phthalic acid.
Which lab setup would be appropriate to use in heating 200 mL of water to the boiling point?
A Bunsen burner setup with a heatproof mat and tripod, along with a beaker containing the 200 mL of water would be suitable. Use a thermometer to monitor the temperature and adjust the Bunsen burner flame as needed to heat the water to its boiling point. Remember to use appropriate safety equipment like goggles and gloves.
How much energy in kilojoules is required to convert 155 mL of water at its boiling point from liquid to vapor delta H vap H20 equals plus 40.7 kilojoules per mole?
The density of water @ 100oC (boiling point) is about 0.958 g/ml. First we need to convert the 155 ml to mass by multiply by the density.155 ml * (0.958 g/ml) = 148.49 gramsNext convert the grams to moles by dividing by the molecular weight of water, which is 18 g/mol:148.49 grams /(18 g/mol) = 8.25 mol of H2OFinally multiply the moles of water by the heat of vaporization (Hvap) to get the final answer:8.25 mol * (40.7 kJ/mol) = 335.775 kJ
How Much energy does it take to boil 100 ml?
The energy required to boil 100 ml of water at room temperature (20°C) to boiling point (100°C) is about 4200 joules. This is the amount of energy needed to raise the temperature of water by 1°C per gram.
How do you find the volume of a solid object like a rock by using water?
put it into water that is in a larger tube or beaker that has measurement markings. measure the water to a nice even amount of mL. carefully place rock into water, remeasure mL. subtract starting point from ending poin, the difference is the mL of the rock. remember, one mL is one centimeter cubed.
