I want to prepare five soil samples with incremental water contents starting from zero percent up to 100 percent. As I want to calibrate and validate capacitive soil moisture sensor SKU:SEN0193

I have dried the soil In the oven, but I am not sure how to add the water to achieve the required gravimetric moisture content by mass Not by volume.

Do I just calculate as if I need 100g/g of moisture content so I add 100g of water for every gram of soil (brown clay).

And I am mixing the soil in a pan by hand.

Thank you
