50mL minus the volume of 0.3 moles pure HCl is how much water is necessary. Be sure to add acid to water never water to acid.

How do you made nickel sulphate?
1. Tie hair up, put lab coat on and put goggles on. 2. Get a 50cm3 beaker and measure 25cm3 of sulphuric acid 3. Measure 3 grams of the nickel carbonate on the weighing scale and add it to the sulphuric acid. 4. Stir continuously with a glass rod until the reaction is complete and no color change is occurring. 5. Get a conical flask with a funnel and filter paper and filter the solution which was made. 6. When filtration is complete add solution to a beaker and heat under the safety flame of a Bunsen burner 7. After 2/3 of the solution has evaporated stop the Bunsen burner and leave solution. 8. Wait a week and crystals are formed with the name nickel sulphate.
What are the procedures for extracting iron from spinach titration?
1. wiegh approximately 15g of spinach 2. using scissors, cut the leaves into small pieces and place in a 250cm3 beacker ( if frozen simply place in beacker) 3. using a measuring cylinder, add 50cm3 1.0 moldm-3 sulphuric acid ( CARE irritant) and boil the mixutre gently for 5 mins 4. allow mixture to cool then filter it, using a buchner funnel and vacuum filtration . wash the residue in the funnel one with a little distilled water to collect all the filtrate 5. pour all the filtrate and washing s into a 100cm3 volumetric flask. make up to 100cm3 with 1.0moldm-3 sulphuric acid. stopper the flask and shake it well. 6. fill the burette with potassium manganate (VII) solution (CARE stains cloths) 7. using a pippette transfer 10cm3 of the spinach extract solution to the 250cm3 conical flask and add 50cm3 of 1.0 moldm03 potassium manganate (VII) solution from the burrette until pink colour persists for 30 seconds. lol i hope that helps lol
Why add 50cm3 of water and 50cm3 of alcohol it would not add up to 100cm3 of liquid?
There are several possible reasons:Inaccuracy in measurement in the smaller amounts could give rise to a combined apparent error in the larger amountSome trace amounts of fluid may be left behind in the beakers that were used to measure the fluidIf the two fluids are not the same temperature, there could by a small amount of thermal expansion/contraction when the fluids are mixedSome fluid could be lost to evaporation, especially true of alcohol
Which apparatus would be useful for collecting 50cm3 of gas?
Pipette

How many ml of ethyl alcohol in 50ml rubbing alcohol?
It is prepared from a special denatured alcohol solution and contains approximately 70 percent by volume of pure, concentrated ethanol (ethyl alcohol) or isopropanol (isopropyl alcohol), so approximately 35 mL in a 50mL bottle.
Can a 45cm3block fit in a 50cm3 space?

How much sugar can dissolve in 50cm3 of water at 75 degrees centrigrade?
179 g per 100 mls of water.
What is the density of an object that has a mass of 184g and a volume of 50cm3?
Density= Mass/Volume = .183kg/50cm3= .00366 kg / m^3 the above solution is wrong because you have to get the units right density = mass/volume = kg/m^3 = 1000g/1000000cm^3 density = 0.183/0.00005 = 3660Kg/m^3
What is the density of a cube with a mass of 200g and a volume of 50cm3?
Density = mass/volume , so 200/50 = 4 g / cubic cm.
A brick has a volume of 50 cm3 and a mass of 150g What is its density?
Density = Mass/Volume = 150g / 50cm3 = 150/50 g per cm3 = 3 g per cm3
What is the density of an object that has a mass of 184 g and a volume of 50cm3?
The density as defined as the mass per unit volume. Accordingly, the density equals 184/50 = 3.68 g/cm3
