Why you need sampling distribution?
in order to calculate the mean of the sample's mean and also to calculate the standard deviation of the sample's
How do you calculate mineral contents of the sample?
We would need to know what sample you are referring to in order to answer this question.
How do you calculate sample size?
Count up the number of obseravtions made on the experimental units. That is the sample size.
How do you calculate density using a formula?
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
How do you calculate the mean of the sampling distribution of the sample proportion?
i dont no the answer
Why hardness is a intensive?
Because the hardness is not dependent to the size of a material sample.
How do you Calculate the total hardness of water sample that contains ppm magnesium and ppm calcium?
Answer will be (mg/L) as CaCO3 units of ppm are the same as mg/L. Hardness = 2.5(mg Ca/L) + 4.1(mg Mg/L) In this case: 2.5x78.4 + 4.1x104.5 = 624.45 mg/L
Sample problem on speed and its solution?
hardness
What sample of hardness material?
magnets steal
How do you calculate the concentration of oxygen in sample water?
If you want less oxygen breathe it in from the water or get a fish to do it
Is hardness extensive or intensive?
No matter what size a sample is, if is hard, it will still be just as hard. This means that hardness is an intensive properties. Intensive properties do not matter what size of sample is being used. Extensive properties will change if sample size is changed.
What is the relation between hardness and conductivity?
Resistivity R is the inverse of conductivity G, R=1/G.
Which does not cause hardness of water?
Magnesium sulfate (MgSo4) does not cause hardness of water.
How do you get rid of water hardness?
Salt is sometimes used to remove water hardness. Borax and soda are generally used as well to remove water hardness.
Wat salt is responsible for temporary and permanent hardness of water?
Temporary hardness of water: CaHCO3, MgHCO3 Permanent hardness of water: CaSO4, MgSO4
Why you need sampling distribution?
in order to calculate the mean of the sample's mean and also to calculate the standard deviation of the sample's
How do you estimate hardness of water?
The water supplier can provide you the details on hardness level if you are on municipal water systems, If you are using private water then you can get tested in laboratories. You can even measure it with water hardness testing kits which you need to purchase.
