You want to make 1M solution, 20ml volume. 185.281*20/1000 = 3.706g. Answer: dissolve 3.706g MgCl2.5H2O in water to a volume of 20ml First, you need molar mass of NaCl which = 58.45 g/mol.

0.50 g NaCl/ 58.45 g/mol Grams cancel to make 0.0085543 mol NaCl Now, take mol NaCl and divide by the number of liters (L). 100 mL converts to 0.100 L. 0.0085543 mol … Sep 12, 2008 For this you need the atomic (molecular) mass of MgCl2. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. MgCl2= 95.3 grams2.00 moles MgCl2 Ã The molar mass (mass of 1 mole) of MgCl2 is 95.205 g/mol.

Mr NaOH = Ar Na + Ar O + Ar H = 22,99 + 15,99 + 1,01 = 39,99 M NaOH = 39,99 g.mol-1 m NaOH = n NaOH * M NaOH = 3 * 39,99 = 119,97 g Odpověď: K neutralizaci 1,5 molu H2SO4 budeme potřebovat 119,97g NaOH. 4. 1 ml (milliliter) = 1/1000 L (Liter, the official SI unit of volume).Weight of 1 milliliter (ml) of pure water at temperature 4 °C = 1 gram (g) .The gram (British spelling: gramme, abbreviation: g) is a unit of mass in the SI system (metric system). The molar mass of sodium is 22.99 grams/mole or g/mol, and the molar mass of chloride is 35.45 g/mol. Added together, this makes the molar mass of NaCl 58.44 g/mol. Using this conversion factor, you can convert from grams of NaCl to moles of NaCl: H 2 SO 4 + 2NaOH ---> Na 2 SO 4 + 2H 2 O. A key point is that two NaOH formula units are required for every one H 2 SO 4. 1) Calculate moles of NaOH and H 2 SO 4: moles NaOH ---> (3.611 mol/L) (0.02369 L) = 0.08554459 mol moles H 2 SO 4---> (0.8921 mol/L) (0.02910 L) = 0.02596011 mol.

View Ch06answers from INTO 250 at University Of Georgia. First two questions MgCl2 has a molecular weight of 95 g/mol. You want to create 250 mL of a 0.15 M MgCl2 solution. Sep 03, 2015 · Start by calculating the moles of Cl- in each of the two original solutions: 0.015 L X 0.2 mol/L MgCl2 X (2 mol Cl- / 1 mol MgCl2) = 6X10^-3 mol Cl- 0.00128 moles of MgCl2 is formed from 0.00256 moles HCl. Hence, mass of MgCl2 = moles x molar mass = 0.00128 x 95.20 = 0.1219 g. Therefore, 0.1219 g of MgCl2 will be formed from 25.6 mL of a 0.100 M HCL solution reacting with excess magnesium metal.

Proběhne-li takových obratů N, pro veličinu ( platí: ( (mol) = N / NA. Bude-li např. ( = 2 mol, zreagovaly právě dva moly látky A se čtyřmi moly látky B za vzniku šesti molů produktu C. Molární hmotnost. Molární hmotnost M je hmotnost jednoho molu atomů či molekul uvažované látky. Její hlavní jednotkou je kilogram na Pokud je tedy na etiketě označující 0,1 M odměrný roztok NaOH uvedena hodnota f = 1,1234, je skutečná koncentrace tohoto roztoku 0,1 mol.l-1 .
