What is the mass percent of the solution. if An aqueous NaCl solution is made using 138 g of NaCl diluted to a total solution volume of 1.10 L Assume a density of 1.08 g per ml for the solution.?
138 g NaCl 1.10 L= 1100mL 1100mL x 1.08g/mL = 1188 grams TOTAL 138/1188 x 100 = 11.6%
What happens to the temperature of equal volumes of soil and water when they are placed in the sunshine for 30 minits?
I assume that water and soil are separate, rather than a wet soil? The temperature of the dark soil would heat up faster than the water - as dark colours absorb heat.
How many grams of thimerosal are required to make 50 g of 100 percent solution?
I need help with this! the problem says "Thimerosal is an organic compound (gram-molecultar mass = 404.8 g/mol). A .100% solution of thimerosal is sometimes used as an antiseptic. Assume that this solution has a density of 1.00 g/mL." I need help with these two: What mass of thimerosal must be mixed with 25.0 g of water to make a .100% solution? What volume of 0.100% solution contains 0.750 g of thimerosal?
Does NH have basic properties?
I would assume so as the nitrogen could accept more hydrogen, protons, into it's structure. Such as NH3, ammonia, a weak base as it can accept a proton in solution.
What is the molarity of a solution that contains 5.10 mol KNO3 in 4.47 kg?
Without knowing the temperature, we'll assume 1 kilogram = 1 litre of water. Therefore if it is 5.1 mole per litre, it is 5.1 molar.
What is the sum of any number and its opposite?
I assume you mean the additive inverse. The sum of any number and its additive inverse is zero. For example, 7 + (-7) = 0.
How do I prove the additive inverse is unique?
assume its not. make two cases show that the two cases are equal
Assume that a solution forms the product mercury liquid acetate The product formed is?
Assume that a solution forms the product mercury (I) acetate. The product formed is _______.

Is it true that a number is always greater than its opposite?
No, not at all!I'll assume you mean the additive inverse, although the following examples can be adapted to the multiplicative inverse as well.The additive inverse of 5 is -5, and 5 is indeed greater than -5.However, the additive inverse of -5 is 5, and -5 is SMALLER than 5.
Assume that a solution forms the product barium carbonate The product formed is?
insoluable
What is the molarity of a sodium hydroxide solution made by combining 2.0 L of 0.60 M NaOH with 495 mL of 3.0 M NaOH Assume the volumes of the two solutions to be additive.?
2.0 L x 0.60 mol/L = 1.2 moles NaOH0.495 L x 3.0 mol/L = 1.485 moles NaOHTotal moles NaOH = 2.685 moles NaOHTotal volume = 2.0 L + 0.495 L = 2.495 LFinal concentration of NaOH = 2.685 moles/2.495 L = 1.076 M = 1.1 M (to 2 significant figures)
What are explanation based on many observations that are supported by experimental results?
i would assume it is known as a solution
