WO3 + H2 → W + H2O

This reaction is carried out in the lab, and 11.4 g of tungsten are obtained. If the percent yield is 89.4%, what mass of WO3 was used?

Can someone just point me in the right direction w/ this, I need to know the volume of Pb-208, which has a mass of 3.45x10E-22 g and a diameter of 3.5x10e-10 m. I have a lot of questions to answer here but they all require the volume first, so what is the best way to approach this to find the volume in cm3? I'm really confused!

PS: I'm not really looking for the answer just the approach to get to the answer. Thanks

Q1)A car of mass 1200kg travels alone a horizontal straight road. The power provided by the car's engine is constant and equal to 20kw. The resistance to the car's motion is constant and equal to 500N. The car pases through the point A and B with speeds 10ms^-1 respectively. The car takes 30.5s to travel from A to B.

i) find the acceleration of the car at A.

ii) by considering work and energy, find the distance AB.

Q2) A and B are points on the same line of greatest slope of rough plane inclined at 30degree to the horizontal. A is higher up than plane B and the distance AB is 2.25m. A particle P of mass m kg is released from the rest at A and reaches B 1.5 s later. Find the coefficient of friction between P and the plane.

anyone can help me with this working thanks...

The problem with reality is how do we determine when reality started? The big bang is all very well but even if you accept that creation started this way
only our minds are caperble of questioning whether
there was a space for us to occupy. Only our minds question if there was a creator, so. is it possible that reality is linked to our thoughts? and not in a three dimensional form that we actualy see with our eyes(after all someone born blind at birth does not see the realities we see but actually knows the reality we think we see exists because he/she is able to relate to responce's in our own minds). Yeah I know it,s a knafe question, sorry hope you can see what I am getting at.(to do that you will have to interpret my mind and that is another point, because if you can see this question your eyes are open.

On beyond the current periodic table lie all the atoms (Ions actualy) that exist only at high densities.at the interiors of large objects like galactic cores. I argue that if there was a big bang then the existing material is still decompressing from the density of the big bang. As part of the decompression Galactic cores give off material that then proceeds radialy away from the core. As the core turns and the next bit of material is expelled the arms of galaxies are formed.
