Question

Na2so3. Xh2o has 50% h2o by mass. What is the value of x

Answer 1

$\huge{\mathfrak{\purple{Answer}}}$

->>

100g of Na2CO3 was dissolved in 1dm3 of water' so i did mass of Y/ Na2CO3: moles x mr = 0.001355x106= 0.14363g so mass of H2O: 100g-0.14363g= 99.85637g

Answer 2

100g of Na2CO3 was dissolved in 1dm3 of water' so i did mass of Y/ Na2CO3: moles x mr = 0.001355x106= 0.14363g so mass of H2O: 100g-0.14363g= 99.85637g
