What would you need to do to calculate the molality of 0.2kg of nacl in 3kg of water?
To calculate the molality of a solution, you need to know the moles of solute and the mass of the solvent in kilograms. First, calculate the moles of NaCl in 0.2 kg: moles = mass (g) / molar mass. Then, calculate the molality by dividing the moles of solute by the mass of solvent in kg: molality = moles of solute / mass of solvent in kg.
How many 500g in 3kg?
There are 6 units of 500g in 3kg. This is because 3kg is equal to 3000g, and 3000g divided by 500g equals 6.
Which is in dry 2kg in wet it is reamain 1kg and when it burns it should be 3 kg?
The item weighs 2kg when dry but only 1kg when wet, suggesting that 1kg of water weight is lost when the item gets wet. When the item burns, it should weigh 3kg, which means it gains an additional 2kg during the burning process.
What weighs 1kg if it's dry and if it's wet then its weight is 2kg and if burned then its weight is 3kg?
Sulfur is closely match this puzzle. The density of 2 kg sulfur is double than 1 kg water. So if you weigh the sulfur in immersed state, the weight of sulfur will be 1 kg. Sulfur will displace about 1 kg water and will lose the same weight. After taking out of water, 2 kg sulfur will be 2 kg only. When you burn the sulfur, it will combine with 2 kg oxygen and you will get 4 kg of sulfur bi oxide. So it is fairly close to the answer. 3 kg literally means more than 2 kg. May be you know the better answer.
Which has greater density-1kg of platinum or 3kg of gold?
When you compare density, you compare the weight of the materials with equal volume. So you cannot compare the density only by weight. The right answer for this is, Platinum has the density of 19.8 gr/cubic centimeters at room temperature versus Golds 19.3 gr/cm3.

How many 500G are there in 3KG?
There are 6 units of 500g in 3kg. This can be calculated by dividing 3000g (3kg) by 500g, which equals 6.
What would the mass be if an object was 3kg?
The kilogram (kg) is the SI unit for mass. So an object that is 3kg, has a mass of 3kg.
