Question

Can someone teach me about Stoichiometry?

Answer 1

yeah..! whats ur question?

Answer 2

Im going to take my online quiz later and Im not sure if I can answer the questions well. Can I ask some questions later?

Answer 3

umm yeah..!

Answer 4

Answer 8

Here :<

Answer 9

do u know how to solve these type of ques?i mean then i will direct u how to do this.!

Answer 10

Im not so good. Can you show me how?

Answer 11

firstly u gotto check from which compound u have to form the required product. so here in the ques it is given that from 100 g K2PtCl4 u have to find the mass of cisplatin .!

Answer 12

soo using the given equation find the amount of K2PtCl4 and K2PtCl4.. using their atomic mass..!

Answer 13

Can you solve it for me? So that I'll be having my pattern to the next type of question

Answer 14

yeah then what all u have to do i will tell u here--
In K2PtCl4-- atomic mass of k2-78g , Pt-195g , Cl4-142g soo for the compound--425 g
in Pt(NH3)2Cl2--Pt-195 g , Cl-35.5, N-14g , H-1g so the mass of compound--300g

Answer 15

then in 300g of K2PtCl4-->425g of Pt(NH3)2Cl2
soo in 100 g of K2PtCl4--> 425/300*100

Answer 16

can u solve it now?

Answer 17

Yes yes. Thanksssss!

Answer 18

pleasure..!

Answer 19

How about for this question? What would be the possible formula?

Answer 20

the same should be done-- calculate the mass of CaO and CaCO3
here u have been given the mass of CaO and u have to calculate for CaCO3
soo it should be-- xg of CaO--> y g of CaCO3
soo 3.102g of CaO--> y/x*3.102

Answer 21

So the answer would be 1.6 g?

Answer 22

i didnt calculate. but if u did by this method it should b correct..!

Answer 23

Thanks. How to compute the mass of a given element if the percent composition of an element is given?
