If 73.5 mL of 0.200 M potassium iodide solution was required to precipitate all of the lead (II) ion from an aqueous solution of lead (II) nitrate, how many moles of lead (II) ion were originally in the solution? Calculate the moles of chloride ions in 50....
How many moles of ions will be present in 133 ml of 0.150 M solution of sodium chloride (aq)? MOLARITY : The number of moles of a substance in one litre of solution is called its molarity. It is also called as concentration denoted by C. molarity = m...
For simple metal ions in Groups 1 and 2, the value of the positive charge is the same as the group number. For a simple metal ion in Group 13, the value of the positive charge is 3+. For a simple non-metal ion in Groups 15 to 17, the value of the negative charge is 18 minus...
How many Mg2+ ions are in 2.80 moles of MgCl2? How many Mg2+ ions are in 3.31 moles of MgCl2? How many moles of MgCl2 are produced from 3 moles of HCl? How many molecules are in 3.5 moles of MgCl2? Calculate the mass, in grams, of MgCl2 used to prepare a 0.475 L solution which...
Calculate the amount in moles for Cl− ions in 13.4 g of nickel chloride (NiCl2) Grams to Number of Moles: The mass of one mole of a substance is the molar mass of the substance. In other words, when the relative molecular mass of a substance is expressed in grams...

How many moles of chloride ions are in a 1.0 L solution of 1.0 M MgCl2? How many moles of sulfate ions (SO_4^{2-}) are present in 1.3 moles of Al_2(SO_4)_3? How many moles and numbers of ions of each type are present in the following aqueous solution? 497 mL...
An expression used to define the amount of solute dissolved in a solution is molarity, M. It can be mathematically represented by the equation below: {eq}\rm M = \dfrac{n}{V} {/eq} {eq}\rm n {/eq} is the moles of the solute ...
Specfically a mole is 6.02 x 1023 atoms or molecules of an element or compound, respectively. This value is known as Avogadro's number. Answer and Explanation: There are 4.2 moles of chlorine in this sample. 4.2molCl×1molCl1molHCl=4.2molCl Since there is......
The molar mass of a compound defines its mass that constitutes 1 mole of the compound. It can be computed by adding up the molar masses of the elements in the compound. It is worth noting that the subscripts of the elements in the chemical formula are taken into consideration when ...
