First, determine how many moles are present in 3 grams of KCl. Start by looking up the number of grams per mole of potassium and chlorine on aperiodic table. Then add them together to get the grams per mole for KCl. K = 39.1 g/mol Cl = 35.5 g/mol KCl = 39.1 + 35.5 = 74.6 g/...
Nurse Emma measured out 5 grams of potassium chloride (KCL). Using dimensional analysis, calculate how many moles of KCL she weighed out. (Use 2 decimal places in your final answer). \\Hint: must convert grams to moles. You want to...
a. How many moles of NaCl are in 58.5 g NaCl? b. Explain how to make 1L of a 1M NaCl solution. Define the minute volume. What role does ADH play in the final volume of urine? Describe the pH scale a. What does the pH scale measure? b. What is the numerical organization of the...
moles of water in one drop = 0.002775 moles Using Avogrado's Number Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there...
How to Calculate Concentration From Density. Density and concentration both describe the amount of a solute per unit volume of a solvent. The former value measures mass per volume. The latter value measures how many moles of atoms exist per unit volume.
If there are 5 liters of a 3 M solution, how many moles does the solution contain? What is the maximum number of kids a woman can give birth to? Provide evidence. Assume that one strawberry with 3x10^9 cells weighs 16g and that 95% of that weight is water. How much does t...
Question: How many milliliters are in 200 cubic centimeters (cc)? Cubic Centimeter (cc) A cubic centimeter is a unit of volume corresponding to the volume of a cube that is 1 centimeter (cm) on each side i.e. having dimensions 1 cm x 1 cm x 1 cm. The cubic centimeter is an SI...
Canada, for example, uses millimoles per liter, or mmol/L, for cholesterol tests. 7 mmol/L is a very high LDL level. What are the five signs of high cholesterol? If you have high cholesterol, you could have: Peripheral artery disease, or PAD Stroke High blood pressure Type 2 diabetes...
It is defined as the amount of substance that contains as many entities (atoms, molecules, ions, etc.) as there are in 12 grams of carbon-12.2. Formula: The relationship between the number of moles (n), mass (m), and molar mass (M) is given by the formula: n=mM where: - n ...
Calculating the initial concentration of a solution – otherwise known as molarity – is an important process commonly found in the chemical and biochemical world. Molarity is the number of moles of solute per liter of solution. Therefore, you need to determine how many moles of a solute are ...
