How many grams of glusose (molar weight 180) would need to be weighed to give one litre of 2 moles per litre glucose?-2 moles per liter is the same as 2 Molar.
Molarity = mass/molar mass/liter of sol
i have totake it with anatomy..its general chemistry-To answer your question, I would say it depends on a few factors. I would say No if you took it in high school because you have some background. An
Potassium chloride crystallizes in the rock salt structure.
Estimate the density of potassium chloride using the following ionic radii: r(K^+) = 133pm, r(Cl^-) = 181pm.
d = _____ g/cm^3
**I keep gett

A) 0.0167 M
B) 0.674 M
C)
Using the following standard reduction potentials, determine the oxidation-reduction reaction that will occur spontaneously.
Al^3++3e^--------> AlE=-1.66V
Mg^2++2e^--------> MgE=-2.73V-A positive vol
What is the Temp of burning Lithium? Can I make lithium chloride by adding lithium to Sodium hypochlorite (bleach)? Or is it better to make Lithium hydroxide, then add HCL? And can I obtain the solid
A given hydrocarbon is burned in the presence of oxygen gas and is converted completely to water and carbon dioxide. The mole ratio of H2O to CO2 is 1.125:1.000. The hydrocarbon could be
A) CH4.
B) C2
A 1.50-L sample of a gas at STP has a mass of 4.75 g. What is one possible formula of the gas?
A) NF3
B) CO2
C) C2F4
D) NCl3
E) NO2-1.50L x [1mole / 22.4L] = 0.0670mol of gas.
4.75g / 0.0670 = 70.
how to calculate % current efficiency?
In process trials 50g of zinc was produced from solution using a current of 2 amps for 24 hours. Calculate the current efficiency-No. of coulombs passed = 2A x 2
What will the volume of a 0.50 M solution be if it contains 25 grams of calcium hydroxide?
So, I started out doing the problem by using the molarity equation. i converted the 25grams to moles and the
i had completed my inter and i wanna take chmical in btech is it tougher than the others-Well it is because Chemistry is one of the most difficult subjects. You can afford a wrong calculation in maths
A 1.00-L bulb contains a sample of O2 at 25°C and 1.00 atm pressure. A second 1.00-L bulb contains a sample of CH4 at 25°C and 1.00 atm pressure. What is the ratio of the number of molecules of methan
Which of the following species would be expected to function as a reducing agent?
A) ClO4–
B) V2+
C) Cs+
D) Ba2+
E) Zn2+
AND WHY?!!- i dont get it-A reducing agent gets oxidized, so it loses elec
Can someone please explain to me how you figure out how many electrons are transferred in the following reaction.
