A chemistry student needed to prepare 250 mL of 0.147 M CaCl2 for her experiment. She has a stock solution in a bottle labeled "0.64 M CaCl2. How many mL of stock CaCl2 she needs to transfer to the 250-mL volumetric flask in order to get the solution she wanted? mL stock CaCl2 solution. Do NOT enter unit. Report your final answer with 3 SFs.

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

Calculate the number of kilojoules to warm 125 g of iron from 23.5°c to 78.0°c.
