An object of mass 150g occupies a volume of 250cm3 calculate it density?
The object's density is 0.6 g/cm3
If the problem was the cylinder is 250 centimeters3 and height is 10 centimeters what does the 250 centimeters3 stands for?
250cm3 is the volume, in cubic centimeters.
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
How can you prepare 250cm3 of 0.5m mgso4 from stock solution of 2.5m mgso4?
Just put both of them together use your common sense duh😂😂😂
How do you calculate 2.50 g divided by 8.3 g cm3?
2.50g/8.3g/cm3 division is the same as multiplying by an inverse. 250g x 1cm3/8.3g as we have g on the top (numerator) and on the bottom (denominator) they cancel each other out. 250cm3/8.3 --> (250/8.2)cm3 ---> 30.4878 cm3 the result in this case is a volume.
What is 25cm3 in dm3?
(1 cm x 1 cm x 1 cm) = 1 cm3 1 cm = 10 mm (10 mm x 10 mm x 10 mm) = 1,000 mm3 1,000 mm3 = 1 cm3 25 mm3 = (25/1000) cm3 = 0.025 cm3
What is the meaning of standardization of solution?
Standardizing a solution is done to find the precise concentration of the solution. It is often done through titrations between two different chemicals, usually an acid or a base. Standardizing a solution can also be done if you know the concentration, but just want to double check it.
500cm3 of ideal gas at 40 degrees Celsius and 200kpa absolute is compressed to 250cm3 and cooled to 20 degrees Celsius.What is the final absolute pressure?
Assuming the amount of gas remains constant, we can use the ideal gas law to calculate the final absolute pressure. The initial pressure (P1) is 200 kPa and the final volume (V2) is 250 cm3. The initial temperature (T1) is 40 degrees Celsius or 313.15 Kelvin, and the final temperature (T2) is 20 degrees Celsius or 293.15 Kelvin. Using the equation (P1 * V1) / T1 = (P2 * V2) / T2, we can solve for the final absolute pressure (P2), which is approximately 400 kPa.
