Sample Report: Lab 1
Data
Part 1: Brewing the Coffee
Mass of empty French press: 529.31 g
Mass of coffee grounds, \(m_g\): 564.30 - 529.31 = 34.99 g
Mass of water added, \(m_w\): 719.44 - 227.44 g = 492.00 g
Mass of brewed coffee, \(m_c\): 648.59 - 227.44 = 421.15 g
Mass of spent grounds, \(m_{\rm sg}\): 624.32-529.31 = 95.01 g
Part 2: Analysis
Brew ratio:
\[ R_{\rm brew} = \frac{m_w}{m_g} \]
Mass of water, \(m_w\): 492.00 g
Mass of dry coffee grounds, \(m_g\): 34.99 g
\[ R_{\text{brew}} = 14.06 \]
